I'm trying to setup environtment for ruby project.
But when I run 'bundle', I have error during installing 'fii' gem:

Please, help me to fix it.
Make sure that you have installed Apple Xcode and Command Line Tools (look at this screenshot):

After that, don't forget to install libffi.
1) if you are using homebrew
brew install libffi
2) if you are using macport
sudo port install libffi
I'm attempting to install charlock_holmes on my Mac (10.7.5, ruby-1.9.3-p392), and I'm encountering the following error:

I've installed icu via macports, so my icu directories are /opt/local/lib/icu and /opt/local/share/icu. I've tried installing with the directories specified:
$ gem install charlock_holmes -v '0.6.9.4' -- --with-icu-dir=/opt/local/lib/icu --with-opt-include=/usr/local/include/ --with-opt-lib=/usr/local/lib/
..but I hit the same error. Any ideas would be welcome.
I was able to install this gem using the version of ICU installed with macports and pointing --with-opt-include and --with-opt-lib to subdirectories of /opt.
The gem successfully installed by running:
gem install charlock_holmes -v '0.6.9.4' -- --with-icu-dir=/opt/local/lib/icu --with-opt-include=/opt/local/include/ --with-opt-lib=/opt/local/lib/
I ran into this issue today. I realize that the original issue was resolved by switching to Homebrew. That wasn't an acceptable solution to me, so I kept digging. The solution was actually quite simple.
After installing icu via Macports, simply install charlock_holmes by running:
gem install charlock_holmes -- --with-icu-dir=/opt/local
Hopefully this helps others that encounter this issue and are not willing to abandon Macports in order to solve it.
I ended up switching from MacPorts to Homebrew and reinstalling my rubies and packages.
I have done all kinds of research and tried many different things. I know this question has been answered many times, but none of the suggested solutions are working for me.
After upgrading to Lion I am getting segmentation faults in Ruby. I'm fairly confident it's Nokogiri. So I installed libxml2 via Homebrew. I ran brew link libxml2. Then I reinstalled Nokogiri using that version of the library.
For proof:
$ nokogiri -v
# Nokogiri (1.5.0)

I've already included Nokogiri at the top of my gemfile and I've also required it in my environment file. I have no idea why I am still getting that warning.
Any suggestions or ideas to make sure it's loading the right version libxml2?
If you installed Nokogiri with gem install nokogiri, you can resolve this warning by running gem pristine nokogiri to recompile the gem's C extension.
If you installed Nokogiri with bundle install, you can resolve this warning by running bundle exec gem pristine nokogiri to recompile the C extension of the gem wherever Bundler installed it.
To fix this if you're using homebrew and bundler, add gem 'nokogiri' to the top of your Gemfile, then run these commands:
gem uninstall nokogiri libxml-ruby
brew update
brew uninstall libxml2
brew install libxml2 --with-xml2-config
brew install libxslt
bundle config build.nokogiri --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26/
bundle install
If you don't use bundler, run these commands instead:
gem uninstall nokogiri libxml-ruby
brew update
brew uninstall libxml2
brew install libxml2 --with-xml2-config
brew install libxslt
gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26/
In your app, you should require nokogiri first, to force the app to load the dynamic libxml2 library instead of the older system version of libxml2 loaded by gems that failed to specify which library to load.
I just spent the better part of the morning working through this warning. This fix is for people using Mac OS Lion. The fix above using
bundle config build.nokogiri --with-xml2-include=/opt/local/include/libxml2 --with-xml2-lib=/opt/local/lib --with-xslt-dir=/opt/local
is for Snow Leopard with libxml2 installed via MacPorts.
With Lion, libxml2 is loaded as part of the bootstrap process. Regardless of which libxml2 Nokogiri is pointing to, the Lion system default library for libxml2 will be used at runtime. Lion uses libxml2.2.7.3 found in /usr (not /usr/local).
As mentioned many other places, one can just ignore the warning. If, like me, the warning drives you crazy, you can do this:
bundle config build.nokogiri --with-xml2-dir=/usr --with-xslt-dir=/opt/local --with-iconv-dir=/opt/local
Interestingly, if you type nokogiri -v at the command line you will get the opposite warning:
WARNING: Nokogiri was built against LibXML version 2.7.3, but has dynamically loaded 2.7.8
This suggests there is more to how libxml2 is being loaded, with Ruby and Rails using the system loaded libxml2 and the command line using libxml2 from the environment path. Anyway, this silences the error for me.
I’ll say it again – this is only for Lion. The previous fix will work for Snow Leopard.
This is the end of the answer. Stop reading here.
OK, you didn’t stop reading... well...
NOT RECOMMENDED!!!!!!
You have been warned. You can verify that Mac OSX is loading the libxml2 library in its bootstrap by disabling libxml2 found in /usr/lib. Do something like copying all versions of libxml2*.dylib to libxml2*.dylib.old (on my machine this was libxml2.2.7.3, libxml2.2 and libxml2).
After you have done this, running Nokogiri will not produce any errors. That is because it can’t find the loaded libxml2 and will now follow the environment path, eventually finding libxml2.2.7.8 in /opt/local.
BUT you won’t be able to copy the old libxml files back. This is because the OS needs the libxml2 that was loaded in the bootstrap.
Powering off and powering on again will brick your machine. The login screen will hang and hang and hang. Power off and power on again in single-user mode (hold Command-S while rebooting). You can watch the bootstrap occur. Low and behold, it throws an error that it can’t load libxml2 and then stops working.
Power off and power on again. This time boot into recovery mode (either hold Command-R or hold Option and then select the recovery disk). In recovery mode open the terminal (utilities/terminal). Mount /usr/lib on your HD (try /Volumes/Macintosh\ HD/usr/lib) and copy the libxml2 files back. Reboot and all will be fine.
None of this worked for me.
I had libxml2 installed at a later version (2.7.8) with brew. This caused nokogiri to compile against it and the later problems. Solution, remove it, then build, then install if desired.
Here's what worked:
brew uninstall libxml2 (if previously installed)
gem uninstall nokogiri
gem install nokogiri
brew install libxml2 (optional)
The solution (for me) after updating to Mountain Lion was much simplier:
gem uninstall nokogiri
# (and ignore the warnings about dependencies)
gem install nokogiri
As per the comment from patrickmcgraw above, simply putting nokogiri as the first entry in my Gemfile worked for me. I'm putting it as a separate answer because the original comment has been buried.
source 'http://rubygems.org'
gem 'nokogiri'
gem 'rails', '3.0.20'
etc...
Bundler has options to set the default build locations. So for instance, with libxml2 installed via macports:
$ bundle config build.nokogiri --with-xml2-include=/opt/local/include/libxml2 --with-xml2-lib=/opt/local/lib --with-xslt-dir=/opt/local
After doing this and bundle install, the warning went away.
There's also some helpful examples for setting build options on the nokogiri wiki.
Looks like you have updated your system libraries after installing the gem, so you have to update Nokogiri. To use the current lib version:
gem install nokogiri -- --use-system-libraries
I had similar problem and just solved this way:
In my case, I have RVM installed, and I had #global and #project gem sets.
Both of them had nokogiri installed and one of them had built with with different libxml.
Rebuilding both of them (I have reason to do this) solved the problem.
Hope this helps..
gem uninstall nokogiri
bundle #install nokogiri again
If that fails with "libxml2 is missing." and you see gems/nokogiri-1.5.0/ext/nokogiri/mkmf.log trying to use "/usr/bin/gcc-4.2 ...", then you're missing /usr/bin/gcc-4.2
Solution:
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
Before:
$ ll /usr/bin/gcc*
lrwxr-xr-x 1 root wheel 12 Jan 15 00:16 /usr/bin/gcc -> llvm-gcc-4.2
After:
$ ll /usr/bin/gcc*
lrwxr-xr-x 1 root wheel 12 Jan 15 00:16 /usr/bin/gcc -> llvm-gcc-4.2
lrwxr-xr-x 1 root wheel 12 Jan 15 21:07 /usr/bin/gcc-4.2 -> /usr/bin/gcc
If you're really missing libxml2 libxslt, then
brew update
brew install libxml2 libxslt
brew link libxml2 libxslt
bundle config build.nokogiri --with-xml2-include=/usr/local/Cellar/libxml2/2.8.0/include/libxml2/ --with-xml2-lib=/usr/local/Cellar/libxml2/2.8.0/lib/ --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26/
bundle
FYI: I'm running Mountain Lion with brew, and bundler.
gem install libxml-ruby helps me
I actually had 2 versions of libxml installed, one from source, one from an RPM.
The following is my complete solution
I uninstalled source (from the source directory)
sudo make uninstall
Remove bundles
rm -rf ~/.bundle ~/.bundler
Updated LD (might have to do this as root, not sudo)
sudo ldconfig
Then reinstalled the bundle
bundle install
Just ran into this myself (OS X Lion 10.7.5). My exact message was: Nokogiri was built against LibXML version 2.8.0, but has dynamically loaded 2.7.3
I tried a few suggestions mentioned here, none worked, but this did:
gem install nokogiri -- --with-xml2-dir=/usr --with-xslt-dir=/opt/local --with-iconv-dir=/opt/local
The explanation is: "This happens because the Lion system default libxml2 (loaded at bootstrap) is used, regardless of which libxml2 Nokogiri was built against."

If you have this message and your nokogiri is out-of-date with the version available from the gem source, simply run bundle update nokogiri to get the new code and recompile. Your error should go away.

After following a lot of help found around the web including building and installing libxml2 and libxslt using brew and building libiconv from the sources (as described in "Installing Nokogiri"), the error remains the same.
When trying to run the installation for Nokogiri, libxml2 and libxslt seem to be found fine, but not libiconv.
Anyone with a better knowledge of these things know how to get Nokogiri installed?
I had the same issue. Unfortunately the "Installing Nokogiri" doesn't cover Iconv issues. Here's how I resolved the issue.
First install homebrew, it'll make your life easier. If you already have it installed, be sure to grab the latest formulae by updating like so:
brew update
Note: In OSX 10.9+ you may need to install xCode command tools to allow you to install libiconv.
xcode-select --install
then install a newer version of libiconv
brew install libiconv
then install your gem
gem install nokogiri -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14
Try using the system libraries. OSX comes with libiconv in newer versions, but the defaults install script seems to have a problem
gem install nokogiri -- --use-system-libraries
Edit: If using bundler, as mentioned by Geoff you can do:
bundle config build.nokogiri --use-system-libraries
#Cory's solution contains the correct answer, but the solution on Mavericks is actually much simpler than the top solution so I'm reposting with only the necessary steps.
On Mavericks (OSX 10.9+):
Install Xcode Command Line Tools:
xcode-select --install
then install your gem:
gem install nokogiri
I was finally able to solve this problem. None of the above solutions completely fixed it for me.
I was getting this error when trying to gem install nokogiri on OSX Lion 10.7.2. First of all, this error masks the real problem by saying libiconv is missing, because you will get the same error even if nokogiri can't find libxslt or libxml2, which in my case, it couldn't.
So I followed the instructions on http://nokogiri.org/tutorials/installing_nokogiri.html under the Homebrew section (slightly modified to account for a more current version of libxml2):
brew install libxml2
brew link libxml2
# install libxslt from source
wget ftp://xmlsoft.org/libxml2/libxslt-1.1.26.tar.gz
tar -zxvf libxslt-1.1.26.tar.gz
cd libxslt-1.1.26
./configure --prefix=/usr/local/Cellar/libxslt/1.1.26 --with-libxml-prefix=/usr/local/Cellar/libxml2/2.7.8
make
sudo make install
At this point I followed the directions on the nokogiri site and tried
gem install nokogiri -- --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26
However, this still failed because when building libxslt from source, it installs the /include folder in a funky place. So you need to specify the lib and include folders separately like so:
gem install nokogiri -- --with-xslt-lib=/usr/local/Cellar/libxslt/1.1.26/lib --with-xslt-include=/usr/local/Cellar/libxslt/1.1.26/include/libxslt
This still didn't work (same libiconv error), so I tried to specify all three required libraries (libxslt, libxml2 and libiconv):
gem install nokogiri -- --with-xslt-lib=/usr/local/Cellar/libxslt/1.1.26/lib --with-xslt-include=/usr/local/Cellar/libxslt/1.1.26/include/libxslt --with-iconv-dir=/usr/local/Cellar/libiconv/1.14 --with-xml2-dir=/usr/local/Cellar/libxml2/2.7.8
Now I got a different error! It was still an error but at least it was different. The make process failed with:
in /opt/local/lib/libz.1.dylib, file was built for unsupported file format which is not the architecture being linked (x86_64) for architecture x86_64
Uhh, what? After a lot of googling, I came across this miracle post: http://www.refresherate.com/2010/01/08/fixing-ld-warning-in-usrlocalliblibz-dylib-file-is-not-of-required-architecture/
Apparently OSX Lion ships with some bad versions of the libz library (libz.dylib, libz.1.dylib, libz.1.2.4.dylib) and and they need to be replaced with the latest versions from the Xcode SDK. The article explains it better than I can so read the above link for specific instructions.
Once these were replaced, I ran
gem install nokogiri -- --with-xslt-lib=/usr/local/Cellar/libxslt/1.1.26/lib --with-xslt-include=/usr/local/Cellar/libxslt/1.1.26/include/libxslt --with-iconv-dir=/usr/local/Cellar/libiconv/1.14 --with-xml2-dir=/usr/local/Cellar/libxml2/2.7.8
again and all was well. I hope this helps someone else.
Just adding my voice to the crowd, but mkmf.log said something about not being able to find symbols for x86_64 architecture. I stumbled across this solution:
sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri -- --use-system-libraries
May not solve anything for the original asker, but this may help someone.
Side Note: nokogiri has been my highest barrier to using ruby applications. Every time someone depends on a different version I have to figure out how to build it. And my problem is different every time.
gem install nokogiri -v '1.6.6.2' -- --use-system-libraries --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
this worked for me on macos.
It works also with version 1.6.6.4
I'm using..
OS X 10.9.4
Homebrew 0.9.4
Here is my summery from this thread to successfully install nokogiri, fixing missing libiconv.
Install Homebrew http://brew.sh/
Or update to latest using command below
brew update
Install libxml2 libxslt
brew install libxml2 libxslt
Link both libxml2 libxslt
brew link libxml2 libxslt
If you get warning to use --force, just use command below
brew link --force libxml2 libxslt
Install xCode command tools to enable you to install libiconv
xcode-select --install
Install libiconv
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
tar xvfz libiconv-1.13.1.tar.gz
cd libiconv-1.13.1
./configure --prefix=/usr/local/Cellar/libiconv/1.13.1
make
sudo make install
Final step, install nokogiri!
gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.8.0/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.8.0/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 --with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib
I solved this on Yosemite running Ruby 2.1.4 by
ensure you have xCode 6.1 installed, then
xcode-select --install, then
In the AppStore click on updates and install the most recent version of the command-line tools (which apparently xcode-select --install does't do - sigh)
then bundle install worked as normal.
I also did a brew install libiconv too but I am not convinced that step was needed.
I tried many things but nothing worked for me. Then I finally found the iconv documentation and it saved my day!
Looking in the mkmf file, it apear that nokogiri (or gem, I don't know) try to find dependencies in /op/local/. For me it's not the right path to search them for.
Forcing nokogiri to find the libs at the right place (I use homebrew) did the trick for me :
$ gem install nokogiri -- --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 --with-xml2-dir=/usr/local/Cellar/libxml2/2.7.8/
Maybe there is something to fix in nokogiri...
HTH,
libiconv was removed from Homebrew 0.9 Now it's recommended to compile libiconv from source, then reference the install when you install the nokogiri gem. See the Nokogiri install instructions under the Homebrew 0.9 section on the Nokogiri install page
Look in the mkmf.log file in the gem's build directory (e.g. /Library/Ruby/Gems/1.8/gems/nokogiri-1.4.4/ext/nokogiri/mkmf.log). That has a lot more info. In my case when I hit this it was that Nokogiri specifically adds /opt/local/lib to the library search path and GNU Backgammon had installed an incompatible libiconv there.
Assuming you installed libxml2 and libxslt with MacPorts, then you might still be getting this error due to a mismatch of the order of include paths and link paths used by the call to have_func('iconv_open', 'iconv.h')
Simple (patch) solution: delete libiconv.* in /usr/local/lib
$ gem install nokogiri -- --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 --with-xml2-dir=/usr/local/Cellar/libxml2/2.7.8/
same as above, this is the solution for homebrew and using gem install (apply changes depends on your version)
however, if you use Gemfile and bundle install, you should apply the bundle config before you install, here the code
$ bundle config build.nokogiri --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 --with-xml2-dir=/usr/local/Cellar/libxml2/2.7.8/ --with-iconv-dir=/usr/local/Cellar/libiconv/1.14
again, apply changes depends on your version
hope this will help you.

I had similar trouble on Mountain Lion. Turns out I had installed libiconv via rvm package previously and this is no longer necessary for ruby 1.9.3/Mountain Lion/nokogiri.
Following the advice of https://rvm.io/packages/, I deleted my $rvm_path/usr directory and rebuilt ruby 1.9.3. Thereafter installing nokogiri was a simple gem install. No messing with brew/macports/manual source installs!
You could also do this on Mavericks:
gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2
Just make sure you have xcode installed
I was fighting with Nokogiri for a while today on OS X 10.10 Yosemite
My environment was messed up for some reason.
which bundle and which gem were giving me /usr/bin/bundle and /usr/bin/gem instead of ~/.rbenv/shims/gem
What helped correct it for me was sudo rm -i /usr/bin/gem /usr/bin/bundle
After that I:
1. switched back to my project directory
2. uninstalled the dependent
3. (re)-installed the dependent libs: did a brew install libxml2 libiconv libxslt
4. installed my ruby version fresh (with rbenv)
5. did gem install bundler
6. and bundle install ran without any problems.
Nokogiri was fine after that.
For reference:
╰─% cat .bundle/config
---
BUNDLE_PATH: vendor/bundle
BUNDLE_DISABLE_SHARED_GEMS: '1'
BUNDLE_JOBS: 4
╰─% which ruby bundle gem
~/.rbenv/shims/ruby
~/.rbenv/shims/bundle
~/.rbenv/shims/gem
This one worked for me
sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri:1.6.6.2 -- --use-system-libraries --with-xml=/usr/local/Cellar/libxml2/2.9.3/ --with-iconv-dir=/usr/local/Cellar/libiconv/1.14
You need to upgrade your homebrew to 0.9
then follow these steps
brew install libxml2 libxslt
brew link libxml2 libxslt
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
tar xvfz libiconv-1.13.1.tar.gz
cd libiconv-1.13.1
./configure --prefix=/usr/local/Cellar/libiconv/1.13.1
make
sudo make install
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.0/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.0/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 --with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib
You should double check the folder library version.
HOMEBREW USERS
Correct solution to fix this problem if you are using homebrew:
xcode-select --install
Choose "Get Xcode" from the dialog box.
brew unlink libiconv
gem install nokogiri
The xcode-select step fixes your Xcode installation and Xcode Command Line Utils installation. I found that I didn't have /usr/include/iconv.h due to some kind of problem with O/S upgrades or restores from backups. If you don't have that header file and /usr/lib/libconv.dylib after running xcode-select then you most likely need to drag Xcode from the Application folder to the trash and reinstall and then manually download the Command Line Tools for Xcode from https://developer.apple.com/downloads/index.action and install that.
Then you need to unlink the libiconv from homebrew. You don't need this. And clang will actually pick up /usr/local/include/iconv.h over /usr/include/iconv.h and will #define iconv_open to libiconv_open but then link against /usr/lib/libiconv.dylib which does not have libiconv_open which is what causes the mkmf failures to find libiconv. What you need to do is remove the linking in of iconv.h so that nokogiri will not find it.
Then just build nokogiri normally.
For new users, all you should need to do is install xcode with xcode-select and install nokogiri, but if you've found this question then presumably you've got a botched installation and not a fresh install of Mavericks.
Some of the other answers here are definitely incorrect. Most of them attempt to use libiconv out of homebrew which is entirely unnecessary. The answers that brew link libiconv are actually causing the problem where clang becomes confused and tries to read a homebrew header file and link against the system libraries. The answers which suggest --use-system-libraries are poor because nokogiri needs to be linked against its bundled libxml2 and libxslt libraries because other versions of those libraries are incompatible with it. The answers which want you to compile from sources are just hopelessly overly complicated.
TL;DR:
Upgrade and/or repair your Xcode installation
Unlink your homebrew libiconv since trying to use that only causes problems
Build nokogiri normally
RVM USERS
Old RVM installations may have a libiconv hiding in your rvm directories somewhere which are conflicting with your system libraries. See https://stackoverflow.com/a/11809261/506908 for more information.
MacPorts USERS
If you have /opt/local/lib/libiconv.dylib then nokogiri adds that path to the list of directories that it searches for and it will find the MacPorts installation similar to how it picks up the homebrew libiconv and conflicts with the system libraries. You can try:
sudo port uninstall libiconv
If that fails due to dependencies then you can try linking against the MacPorts version directly (untested):
gem install nokogiri -- --with-iconv-dir=/opt/local
I ran into this, this morning... after an upgrade to Mavericks. We did many things. However if anyone is having this issue here are some things to try.
I ran 'xcode-select --install' then got the command line tools installed (surprised this didn't update on the OS ugrade).
I ran 'rvm implode' (I will build it back up later).
We pieced together two error output files:
~/.vagrant.d/gems/gems/nokogiri-1.6.3.1/ext/nokogiri/gem_make.out
~/.vagrant.d/gems/gems/nokogiri-1.6.3.1/ext/nokogiri/tmp/x86_64-apple-darwin12.5.0/ports/libxml2/2.8.0/configure.log
Which seemed to indicate that the c compiler was using a surprising setting.
I ran 'env'
Output contained:
...
CXX=/usr/local/opt/apple-gcc42/bin/g++-4.2
...
CC=/usr/local/opt/apple-gcc42/bin/gcc-4.2
...
These files didn't exist on the file system...
After all of these changes moving to a new terminal windows (so everything was fresh). Installation of vagrant-berkshelf (which in turn installs nokogiri) worked fine.
NOTE: when running 'env' in the fresh window there was no longer a setting for CC or CXX...
Unsure on the key part of this, or if order matters, but tried to recreate the parts that seemed to play a role in getting this to work.
According to the documentation, as of OSX 10.9 and Homebrew 9.5+, you are probably missing the development tools.
Nokogiri installation
Troubleshooting
If you have problems mentioning libiconv missing that looks something like this:
Installing nokogiri (1.6.2.1) Building nokogiri using packaged libraries.
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/usr/local/rvm/rubies/ruby-2.0.0-p0/bin/ruby extconf.rb
Building nokogiri using packaged libraries.
checking for iconv.h... yes
checking for iconv_open() in iconv.h... no
checking for iconv_open() in -liconv... no
checking for libiconv_open() in iconv.h... no
checking for libiconv_open() in -liconv... no
-----
libiconv is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.
-----
*** extconf.rb failed ***
Then you are probably missing the right developer tools. This is a really easy fix:
brew unlink gcc-4.2 # you might not need this step
gem uninstall nokogiri
xcode-select --install
gem install nokogiri
This is verified working on OSX 10.9 w/ xcode’s clang compiler.
I got this issue when I upgraded my Mac OS to Yosemite. I was able to solve this issue by doing:
xcode-select --install
brew uninstall libiconv
brew install libiconv
gem install nokogiri
I had a similar issue and the accepted answer used to work for me. Now, however I have been seeing a new error message where a gmkdir command is missing as in this question:
gem install nokogiri -v '1.5.11' failed due to make: /usr/local/bin/gmkdir: No such file or directory
What worked for me was first a little cleanup:
brew uninstall libiconv
brew uninstall libxml2
brew uninstall libxslt
And then brew unlink libiconv and whatever else you need to unlink (check with brew doctor). Then, the magic two lines (copied from the linked answer):
brew install coreutils
gem install nokogiri
Simple steps to follow before you start uninstalling and installing anything.
Check if you have CLT (command line tools installed):
brew config
see the CLT version here if its installed no need for reinstallation.
This means the issue is with permission you have reinstall only bundler gem make its not sudo.
Uninstall bundler with
gem uninstall bundler
reinstall gem bundler
gem install bundler
Most important point here is the permission under which bundler gem is installed it should never be sudoed.
First of all make sure you follow the installation guide on nokogiri: http://nokogiri.org/tutorials/installing_nokogiri.html
After having followed the guide I still had this issue. This is how I solved it:
First of all I installed iconv using homebrew:
brew install iconv
Then I uninstalled ruby, luckily this is very easy with rvm:
rvm uninstall 1.9.2
Then I had to reinstall ruby with the following options:
CC=gcc-4.2 rvm install 1.9.2-p290 --with-iconv-dir=/usr/local/Cellar/libiconv/1.13.1
Then I create a gemset with the new ruby version:
rvm use 1.9.2#coolproject
Then I can finally install nokogiri like this:
gem install nokogiri -v=1.4.4 -- --with-xml2-include=/usr/local/Cellar/libxml2/2.7.8/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.7.8/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26
In my case, (as with scotchi) the build failed because of an incompatible iconv library in /opt/local/lib.
By default, theNokogiri build process looks at /opt/local first.
To force it to use a different install directory, /usr/local for example, do:
gem install nokogiri -- --with-xml2-lib=/usr/local/lib --with-xml2-include=/usr/local/include/libxml2 --with-xslt-lib=/usr/local/lib --with-xslt-include=/usr/local/include
This blog post proposes to install libiconv manually.
Subsequently, nokogiri can be installed with a number of switches telling it where to find libiconv (see the blog post).
As a side note: After installing nokogiri, I managed to install gollum (installation of which also failed because it could not find iconv). Now I am still facing problems though, because when I start up gollum, Python crashes.
$ gem install iconv # works but it is missing an iconv.so file in ruby 2.0.0-p247
$ ls -1 2.0.0-p0/lib/ruby/gems/2.0.0/gems/iconv-1.0.3/*/*/*.so

NOW IT WORKS!
$ pry

=> true
I had to install gcc first before running ./configure --prefix=/usr/local/Cellar/libiconv/1.13.1
I want to install a ruby gem which tries to build a native extension. The gem in this case is nokogiri. If I do gem install nokogiri, the native extension dynamically links against libxml, libxslt libs. I want to statically link against those libs. How should I go about this?
Here are some pointers, but's it's not easy unless nokogiri contains build flags to support it:
If nokogiri supports it, you can pass build arguments to install gem like this
gem install nokogiri -- --with-static-libxml
If there is no built in support you can try tweaking linkflags used to install the gem with:
gem install nokogiri -- --with-ldflags='-static'
It's likely that the build will fail, since --with-ldflags overrides all LDFLAGS, and also '-static' tries to link everything as static, so you need to examine mkmf.log, and treat it accordingly.
If you want to do it manually, one way to do it is making the gem install fail by invoking with invalid option like:
gem install nokogiri -- --with-ldflags
This will cause the installation to fail with a message like this:
Building native extensions. This could take a while...
ERROR: Error installing nokogiri:
ERROR: Failed to build gem native extension.
ruby extconf.rb --with-ldflags
So you should be able to build the gem yourself then after it's done finish the installation with (see gem help install):
gem spec ../../cache/nokogiri-1.4.1.gem --ruby > \
../../specifications/nokogiri-1.4.1.gemspec
Try:
sudo apt-get install libxslt-dev libxml2-dev
I resolve this problem.
To install nokogiri gem first you need to install libxslt-dev and libxml2-dev
sudo apt-get install libxslt-dev libxml2-dev
And then install nokogiri gem
sudo gem install nokogiri
Afterwards you need to install the bundle
bundle install
Last but not least the installed gem needs to be defined within your Gemfile
gem 'nokogiri'
These steps worked flawlessly for me.
Error Msg : error: error installing nokogiri: error: failed to build
gem native extension.
I fixed this issue just by running the these two commands :
$ sudo apt-get install libxml2 libxml2-dev libxslt libxslt-dev?
$ gem install nokogiri
And it worked fine..!! :)
If you're using RVM, run rvm requirements and install the list of libraries at # For Ruby / Ruby HEAD.
That should work
I fix this issue by:
sudo apt-get install libxml++1.0-dev
The really issue here is because this nokogiri depends on libxml1, but default install is libxml2....
sudo apt-get install libxslt1-dev libxml2-dev works for me. As of July 31, 2013
