I have openssl installed in my virtual machine ubuntu12.04lts.
When I run the gem command it gives error.
Error: while executing gem (Gem::Exception)
Unable to require openssl. install openSSL and rebuilt ruby (preferred) or use non HTTPs sources
And I also test require openssl in irb mode.
it gives error.
Loaderror: cannot load such file --openssl
from /usr/local/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55 `require'
I have openssl
$openssl version
OpenSSL 1.0.1 14 mar 2012
How to fix the error?
Note: Calls to rubygems.org are deprecated - proceed with caution!
I had the same issue on Mac OSX after also building ruby2.1.0p0 from the source. I already had openssl installed. It appears that the reference in gems needed refreshing. I ran:
gem source -r https://rubygems.org/ to remove
followed by
gem source -a https://rubygems.org/ to read
After this, I was able to run gems install bundler successfully.
If you run into further errors, you can try ./configure --with-openssl-dir=/usr/local/ssl in your ruby downloaded dir/.
I got this error while using debian where openssl was in /usr/bin.
Following the suggestion of jspacek I reconfigured ruby using:
./configure --with-openssl-dir=/usr/bin
After make and sudo make install I was able to install rails.
make sure you have libssl-dev installed:
dpkg -s libssl-dev
if not, install it:
sudo apt-get -y install libssl-dev
In case someone else has this problem, try reinstalling your Ruby version with openssl included
brew install openssl
rvm reinstall 2.4.0 --with-openssl-dir=`brew --prefix openssl`
You might already have openssl - so you can ignore the first step.
This helped me.
I'm leaving this answer for reference to future Googlers:
Type all these commands in your Terminal (OSX) just to be extra sure you've done everything (this is what eventually worked for me)
rvm get stable
brew update
brew doctor
brew install openssl
rvm install ruby-2.1 (or whatever version)
rvm use (ruby version here) i.e. rvm use ruby-2.1
rvm gemset create NAME i.e. rvm gemset create rails41
gem install rails -v 4.1
Finally...
As many commenters have pointed out - you need OpenSSL installed before you compile ruby before you install rails (or other gems)
You probably built Ruby from source before installing OpenSSL. Make sure you install it and then try reconfiguring and rebuilding Ruby.
Recently I was struggling with ruby installations due to the recent auto-update in openssl version from 1.0 to 1.1 and wanted to revert it back to older version. No other solution except the one given below worked for me:
brew install rbenv/tap/openssl#1.0
rvm reinstall 1.9.3-p551 --with-openssl-dir='/usr/local/opt/openssl#1.0'
gem update --system
Now my ruby runs with openssl 1.0 whereas all other libraries are running on the default openssl version 1.1.
Rebuilding Ruby after running sudo apt-get install libssl-dev libreadline-dev libgdbm-dev can solve this issue.
I found this solution here.
I was getting this error installing Ruby with RVM. Nothing worked. I switched to rbenv. Problem solved!
for me it was a case of missing dependencies.
i thought i had all the dependencies required to install ruby, but i too was getting an openSSL and readline error.
i attempted to install ruby with RVM without root privileges which failed but gave me a list of missing dependencies. i then installed the dependencies with a package manager. i then re-attempted to install ruby from source from the beginning, and everything worked OK
the dependencies that were missing, for me, were:
patch libyaml-devel autoconf gcc-c++
readline-devel libffi-devel openssl-devel
automake libtool bison sqlite-devel
but they may be different for you.
update: i don't originally remember where exactly i found this list, but a quick search found similar lists on the following pages, which might also help you:
https://www.digitalocean.com/community/tutorials/how-to-install-ruby-on-rails-on-centos-6-with-rvm
http://www.itzgeek.com/how-tos/linux/ubuntu-how-tos/install-ruby-on-rails-on-centos-ubuntu-fedora-from-source.html
These steps worked for me:
Fixed ruby install:
brew upgrade openssl;
openssldir=which openssl
rvm reinstall ruby-2.4.2 --with-openssl-dir=$openssldir
Removed and re-added sources for gems
gem sources -r https://rubygems.org/
gem sources --add https://rubygems.org/
i had similar issue and tried to solve it by following guides. The "rebuild ruby" is an important step!
after openssl_devel is installed
cd folder_of_ruby_source_code/ext/openssl
ruby ./extconf.rb
make
make install
cd folder_of_ruby_source_code
./configure
make clean <= clean is important here
make
make install
Do you use RVM?
If not, try using it and see if it fixes your problem.
I have OS X Mavericks installed and I'm trying to run rvm requirements in terminal and it gives me this error.
Installing required packages: autoconf, automake, libtool, pkgconfig, libyaml, libffi, readline, libksba, curl-ca-bundle, gdbm.............
Error running 'requirements_osx_port_libs_install autoconf automake libtool pkgconfig libyaml libffi readline libksba curl-ca-bundle gdbm',

Requirements installation failed with status: 1.
It looks like RVM tried to install some dependencies using Macports and Macports proceeded to get really confused about dependencies when it tried to install autoconf.
Try running:
brew install autoconf
Otherwise you should run this bash script:
https://gist.github.com/siraj/1399288
Assuming you have brew, which you should if you don't.
If your Macports just isn't working, then you can manually install all of the requirements like this:
brew install autoconf automake libtool pkgconfig libyaml libffi readline libksba curl-ca-bundle gdbm
I tried the above, and a few other things. None worked.
It seems that on OSX 10.9 and XCode5 moved some libs around on us. So I had to install XCode5-DP6 (Dev Preview 6), opened up DP6 and in the settings, you have to tell the command line tools to use the new DP6 build and not the Standard XCode from the marketplace.
First, I had to install homebrew. Nothing liked to play with macports. I am on my first mac as of only a month ago, so macports was just what solved apache for me at the time. I then had to run 'brew install autoconf'
Once I did that I then ran rvm requirements, everything installed without issue. then sudo gem install jekyll from there and it all works like a charm now.
I'm sure once Mavericks is actually released this will get ironed out. We are using early releases after all...
Hope this works for you guys.
I have been trying to get Ruby to run on my Mac for a few days and whatever I do does not seem to be successful. I have installed MacPorts and followed the post here: Installing Ruby on Mac OS X 10.8.2
I ran the following commands:
sudo port selfupdate
sudo port install apple-gcc42
They completed sucessfully then I ran the line below:
CC=/opt/local/bin/gcc-apple-4.2 rvm install ruby-1.9.3-p194 --enable-shared --without-tk --without-tcl
After I run that line it takes a couple minutes and I get the following:
enter code here MacPorts base is already the latest version
DEBUG: Setting MacPorts sources ownership to root
The ports tree has been updated. To upgrade your installed ports, you should run
port upgrade outdated

Missing required packages: autoconf, automake, libtool, pkgconfig, libiconv, libyaml, readline, libxml2, libxslt, libksba, openssl, curl-ca-bundle, sqlite3, zlib, ncurses, gdbm.
Cowardly refusing to continue, please read 'rvm autolibs'.
There were package installation errors, make sure to read the log.
Do I need to install the missing packages that it references? If so, how do I do this? I'm not very familiar with MacPorts and would appreciate the help to get this working.
Since I originally I went to install RVM through https://rvm.io/rvm/install/ I followed the first command to RVM with ruby:
$ \curl -#L https://get.rvm.io | bash -s stable --autolibs=3 --ruby
After I ran the command it downloaded and compiled then when it went to install rubygems-2.0.3 for ruby-2.0.0-p0 it gave the following error message:
Error running 'env GEM_PATH=/usr/local/rvm/gems/ruby-2.0.0-p0:/usr/local/rvm/gems/ruby-2.0.0-p0#global:/usr/local/rvm/gems/ruby-2.0.0-p0:/usr/local/rvm/gems/ruby-2.0.0-p0#global GEM_HOME=/usr/local/rvm/gems/ruby-2.0.0-p0 /usr/local/rvm/rubies/ruby-2.0.0-p0/bin/ruby -d /usr/local/rvm/src/rubygems-2.0.3/setup.rb --verbose',
please read /usr/local/rvm/log/ruby-2.0.0-p0/rubygems.install.log
I then went to open the log file and at the bottom it says
ERROR: While executing gem ... (NoMethodError) undefined method fu_stream_blksize for #<Gem::Commands::SetupCommand:0x007fa09b05d7a8>
Installing RubyGems

Any ideas what I can do next?
Thanks in advance.
I had similar problems with OS X 10.8.3 and XCode 4.6.1. After some googling, I tried the install with a similar RVM command, except using the XCode version of clang (which symlinks to /usr/bin/cc). Try this:
\curl -#L https://get.rvm.io | bash -s stable #just get rvm
source ~/.rvm/scripts/rvm
rvm get head # update to latest rvm
CC=/usr/bin/cc rvm install ruby
It should have the same failure installing rubygems-2.0.3, but reinstalling just rubygems should work:
CC=/usr/bin/cc rvm install rubygems latest # substitute "2.0.3" for "latest" if you like.
It appears that this is a bug in rubygems which is scheduled for fixing in 2.0.4.
Hope that helps!
I think this bug provide from FileUtils.
To fix it you need change rubygems script from rvm: nano .rvm/scripts/rubygems
To find words in nano use ctrl+w setup.rb and remove --verbose option.
After this you need ctrl+o to save file and ctrl+x to close nano.
Now you may reinstall rubygems:
rvm rubygems remove
rvm rubygems latest
Sorry for my bad english.
Hope this help you.
In addition to Valery's answer, you might have to do the following before removing and reinstalling:
echo ${LANG:-empty}
export LANG=en_US.utf-8
Links to the problem and solution:
https://github.com/rubygems/rubygems/issues/516
https://github.com/wayneeseguin/rvm/issues/1689
This problem is harmless, rubygems is already installed and will work as expected, this is triggered by https://bugs.ruby-lang.org/issues/7992 - with --verbose flag to rubygems installation - your ruby is fully usable if there was no other error during installation.
A side note, RVM detects all the options/flags you have passed and it is not required to pass them manually, it would be enough to run:
rvm install ruby-1.9.3-p194
The RVM installer ran with --autolibs=3 is equivalent to running it withoug and setting it manually with:
rvm autolibs 3
To get more information on autolibs and available modes run:
rvm help autolibs
Using rvm I upgraded my ruby to 1.9.3-p392, also added 2.0.0, anytime I try to use this version when I run my bundle command I get this error.
Could not load OpenSSL.
You must recompile Ruby with OpenSSL support or change the sources in your Gemfile from 'https' to 'http'. Instructions for compiling with OpenSSL using RVM are
available at rvm.io/packages/openssl.
I have followed several different instructions on how to fix this. I have tried removing the version and installing it with the rvm options
--with-openssl-dir=$HOME/.rvm/usr
I have installed OpenSSL with rvm, and macports. Both have not helped the problem. I even changed the file location of the ssl cert using this:
export SSL_CERT_FILE=/Users/DarkLord/.rvm/usr/ssl/cert.pem
No matter what I do I continue to get the error.
Can someone please help me fix this?
This works for me:
rvm get stable
brew install libyaml
rvm pkg install openssl
rvm install ruby-2.0.0 --with-openssl-dir=$HOME/.rvm/usr
rvm use ruby-2.0.0
All credits go to https://coderwall.com/p/tptocq
This helps me install 1.9.3-head on Mac:
rvm get latest
brew install openssl
rvm reinstall 1.9.3-head --with-openssl-dir=`brew --prefix openssl`
In my case after:
1. brew install openssl
2. rvm install ruby-2.6.0
bundle install failed with this error. The problem was that openssl was globally set so I had to install the new ruby version by setting the openssl directory explicitly.
So what I had to do was:
1. rvm reinstall ruby-2.6.0 --with-openssl-dir=/usr/local/opt/openssl
2. rvm reload
Assuming that usr/local/opt/openssl is where it is installed.
After that bundle install ran successfully.
Warning when I tried this command with this path /usr/local like some answers suggested, it didn't work.
To get this working again I had to install homebrew and move my mac ports out of the way. Then do the following after removing 1.9.3-p392 and 2.0.0-p0:
rvm get head --autolibs=3
rvm install 1.9.3 --with-opt-dir=/usr/bin
rvm install 2.0.0
There was something not working with my mac ports and openssl and make and configure. This was the only way I was able to get rvm to install ruby again with out getting openssl issues or make/configure issues.
The new way to do it, according to a comment by #Purplejacket above, is the following:
rvm autolibs homebrew
rvm install 2.1.1
rvm use 2.1.1
It's much easier.
In my case:
Problem: After installing ruby-2.3.1, I ran the command bundle install and then the error occurred.
Solution:
I first installed OpenSSL on my machine. $ brew install openssl
And then, reinstalled the ruby version I require (2.3.1) with the openssl.
$ rvm reinstall 2.3.1 --with-openssl-dir=/usr/local/opt/openssl
And this solved my problem!
According to the following question:
How to tell which openssl lib is actually being used by an RVM-installed ruby
It seems that the options --with-openssl-dir=... is no longer valid as of Ruby 1.9.3. I tried
rvm install 1.9.3 --with-opt-dir=/usr/local --with-openssl
and it worked.
macOS Catalina
brew install rbenv/tap/openssl#1.0
rvm reinstall 2.3.8 --with-openssl-dir=/usr/local/opt/openssl#1.0
The following steps worked for me.
First ensure openssl is installed by running brew install openssl, then reinstall the ruby version using rvm, but this time around, you have to pass the with-opt-dir flag pointing to the location where openssl was installed on your machine (use command which openssl to find this location).
rvm install 1.9.3-p392 --with-openssl-dir=/usr/local/opt/openssl
On macOS 10.14, Ruby 2.5.3, and OpenSSL 1.0.2n this worked for me:
./configure --with-openssl --with-openssl-dir=/usr/local/ssl
but I was only trying what the error messages were telling me:
*** Following extensions are not compiled:
openssl:
Could not be configured. It will not be installed.
/Users/brian/Desktop/Ruby/ruby-2.5.3/ext/openssl/extconf.rb:97: OpenSSL library could not be found. You might want to use --with-openssl-dir=<dir> option to specify the prefix where OpenSSL is installed.

I encountered this issue when working on a Ruby 2.2.3 application.
I had previously uninstalled the MySQL database server on my machine, since I did not need it. However, I still needed the mysql2 gem since my application was connecting to another application's MySQL database to pull data.
However, when I try to run the bundle command I get the error:
Could not load OpenSSL.
You must recompile Ruby with OpenSSL support or change the sources in your Gemfile from 'https' to 'http'. Instructions for compiling with OpenSSL using RVM are
available at rvm.io/packages/openssl.
Here's how I solved it:
The issue was caused by removing the libssl-dev library when I was uninstalling the MySQL database server on my machine and its libraries.
First I ran the command below to reinstall ruby since I installed it using rvm:
rvm reinstall ruby-2.2.3
This raised an error:
Making gemset ruby-2.2.3 pristine............................................./-
.'command gem pristine --extensions mysql2 --version 0.5.3' failed, you need to fix these gems manually.
.
Error running '__rvm_with ruby-2.2.3 gemset_pristine',
please read /home/promisepreston/.rvm/log/1630094455_ruby-2.2.3/gemset.pristine-ruby-2.2.3.log
Next, I tried to install the mysql2 gem:
gem install mysql2
Then I ran into this error:
Building native extensions. This could take a while...
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.
mysql client is missing. You may need to 'sudo apt-get install libmariadb-dev', 'sudo apt-get install libmysqlclient-dev' or 'sudo yum install mysql-devel', and try again.
Finally, I installed the mysql client library using the command:
sudo apt-get install libmysqlclient-dev
Note: This also installs the libssl-dev library alongside.
And everything worked fine.
That's all.
That's what helped me:
rvm reinstall 2.5
brew tap raggi/ale
brew install openssl-osx-ca
brew services start openssl-osx-ca
Found this solution here: https://github.com/raggi/openssl-osx-ca#readme
I specified a more recent Ruby version in my Gemfile, then ran bundle install. All good now.
Specific case for ruby version 3.0.3
By default for brew and system and autolibs OpenSSL version is 3. Ruby 3.0.3 does not work with OpenSSL version 3 and ruby build silently ignores OpenSSL.
To build ruby properly use build options with OpenSSL 1 like this:
PKG_CONFIG_PATH=/usr/local/opt/openssl#1.1/lib/pkgconfig rvm reinstall 3.0.3 --with-openssl --with-openssl-lib=/usr/local/opt/openssl#1.1/lib --with-openssl-include=/usr/local/opt/openssl#1.1/include
Where path variables may be another - check your system.
Thanks to article Ruby 3.0.3 with OpenSSL using MacPorts and RVM
I got this to work on Ubuntu 22.04 by doing:
rvm pkg install openssl
...and adding --with-openssl-dir=$HOME/.rvm/usr to the rvm install command.
This doesn't seem particularly OS-specific and might work on Mac OS as well.
Fix which worked for me
rvm install 3.0.3 --with-openssl-dir=/opt/homebrew/etc/openssl#1.1
PS. Find the correct openssl location in your machine and install ruby pointing to that path like above, mentioning the brew installed openssl#3 path doesnot work.
I don't use rvm, and I don't want to. I had to install asdf in order to resolve what I used to be able to do with just homebrew & ruby.
Following this guide is the only thing that worked for me after following dozens of suggestions. I had to install asdf and update my .zshrc to include the following at the end of the doc:
eval "$(rbenv init - zsh)"
I'm on an Intel Mac running Monterey 12.2.1.
When I try do install rmagick I get the following error message:
Can't install RMagick 2.13.1. Can't find MagickWand.h.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
I'm on Mac OSX 10.6.8, ruby 1.9.2p290, rvm 1.10.2.
Can anyone help me please to solve this problem.
If you're on Ubuntu, installing this package is what fixed it for me:
sudo apt-get install libmagickwand-dev
It looks like ImageMagick 7 changed include file path.
On building rmagick, since it includes file as wand/MagickWand.h There are no workarounds. It looks like sticking with ImageMagick 6 for now.
On Mac OS X (I tested on Sierra), I used HomeBrew's versions tap like:
brew tap homebrew/versions
brew install imagemagick#6
Then, use the path shown on above installation:
PKG_CONFIG_PATH=/usr/local/opt/imagemagick#6/lib/pkgconfig gem install rmagick
To install with ImageMagick 6.
I didn't want to mess with environment variables since I wanted bundler to be able to compile this gem on its own on a CI machine. Instead, I used Homebrew to install pkg-config:
brew install pkgconfig
and the next time I tried compiling the RMagick gem it found the header file without issue.
(This is pkg-config 0.28, ImageMagick 6.8.0-10, and RMagick 2.13.2, all on Mountain Lion.)
I had a similar issue with running
$ gem install rmagick
First of all, do you have imagemagick installed? If you're not sure, run
$ convert --version
If you do, you probably either installed it with fink or macports (maybe homebrew?). What is happening is that rvm can't find the imagemagick directory.
After reading
https://superuser.com/questions/361435/i-have-compiled-imagemagick-on-my-centos-and-rmagick-wont-install
I exported the imagemagick path by adding
$ export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH"
to my ~/.bash_profile, sourcing the new profile, then running:
gem install rmagick
It worked for me after I did this.
fix this setting the include path of your current imagemagick installation:
Install ImageMagick with brew
brew install imagemagick
find library
$ mdfind MagickWand.h
/usr/local/Cellar/imagemagick/6.7.5-7/include/ImageMagick/wand/MagickWand.h
Install rmagick gem
$ C_INCLUDE_PATH=/path/MagickWand.h gem install rmagick
example:
$ C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.5-7/include/ImageMagick/ gem install rmagick
I marked this as a favorite because it seems to come back to bite me with every new system I need to install RMagick on (and time has passed and version numbers have rolled).
Mac OS X 10.8.4
rvm 1.22.3
ruby-2.0.0-p247

Many thanks to everyone who added helpful answers above!
Mac users using brew
If you can use v6 of ImageMagick instead of 7, you can try this
brew install imagemagick#6 --force && brew link imagemagick#6 --force
Note this will unlink your existing IM installation, so be careful if you have other projects on your machine using ImageMagick without problems.
For my own and others edification, I got past the error about the magicwand.h by using the suggestion xonico. MDFind plus the C_INCLUDE_PATH. However, it then gave me an error about MagickCore.pc. My final command to get this working had to include both like so:
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick/ PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/lib/pkgconfig/ gem install rmagick
Obviously your paths will vary depending on whether you're using brew like me and what version of imagemagick you were installing. Also, xcode command line tools did have to be installed, as others have mentioned.
Thanks for everyone's posts on this! I am plussing your answers since it contributed to mine!
For Ubuntu:
sudo apt-get install imagemagick libmagickwand-dev
gem install rmagick
I had a problem after update to Maverics.
It have lost a lot of linkings.
In my case I had to refresh links to pkg-config
brew unlink pkg-config
brew link pkg-config
Then installing rmagick worked like a charm.
I updated to Mountain Lion and started getting this same problem. I had to re-install brew, XCode, the XCode tools - pretty much the whole environment!
I eventually solved this problem using the answer from phopkins above...
brew install pkgconfig
Once that was successfully completed (I had to delete some old symlinks first) then I was able to successfully install the RMagick gem
This worked for me on Mac OsX
Install Imagemagick:
brew remove imagemagick
brew install imagemagick
Make sure pkg-config is correctly linked:
brew uninstall pkg-config
brew install pkg-config
brew unlink pkg-config && brew link pkg-config
Install gem
gem install rmagick
For Ubuntu users:
It will never done directly on Ubuntu. You should first install packages to run this command...:
sudo apt-get install libmagickwand-dev
...and then do install:
gem install rmagick
You may get the same issue, for that, Try clearing your apt repository and removing any broken packages first:
sudo apt-get update
sudo apt-get autoclean
sudo apt-get clean
sudo apt-get autoremove
If the system identifies any broken packages, forcefully remove them (replace package_name with your own):
sudo dpkg --remove -force --force-remove-reinstreq package_name
Then re-install any missing packages again. :)
An issue for me was that rmagick is out of date and not updated regularly. If you have too new of an ImageMagick version, then it might not be compatible. Check your version of ImageMagick using the following:
$ convert --version
If the ImageMagick version is > 7, it is not compatable with rmagick. The user will get errors such as
Can't install RMagick 2.16.0. Can't find MagickWand.h.
*** extconf.rb failed ***
Go back to version six of ImageMagick until they update rmagick to be compatible with version seven of ImageMagick. Someone has hosted the appropriate version(6) in a separate gem - 'imagemagick#6'.
If you need rmagick to work but currently have an imagemagick version 7 or higher, here are the steps to switch:
$ gem install imagemagick#6
$ brew unlink imagemagick
$ brew link imagemagick#6 --force
Helped me on Debian Wheezy 64bit
apt-get install libmagickcore-dev libmagickwand-dev
Try reinstalling both Imagemagick and PkgConfig. That should fix it for Mavericks
brew update && brew upgrade
brew reinstall imagemagick
brew reinstall pkgconfig
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick gem install rmagick
I was really struggling with this on OS X Mountain Lion (after upgrading from Lion) and none of the suggestions regarding C_INCLUDE_PATH, PKG_CONFIG_PATH, ln'ing various files, etc., were working. On the same day I upgraded to Mountain Lion, I also upgraded XCode to 4.5.2, but I didn't really think too much of this.
Eventually I stopped trying to install RMagick and had to pass on the work to a colleague.
Then, by chance, I found that I was trying to use bundle install on another project and I wasn't able to install the json gem because "make" could not be found. I checked into that and found you need to go to XCode -> Preferences -> Downloads and install the command line tools to get make working again. The json gem installed fine.
Then I paused...and tried
gem install rmagick
One more time. It worked perfectly.
for a rails based application, I found this
sudo apt-get install -y libmagickwand-6-headers
C_INCLUDE_PATH=/usr/include/ImageMagick-6 gem install rmagick
bundle update rmagick
bundle install
worked on debian jessie
I ran into this because I'd run OS X's Migration Assistant and nothing was relinked after the migration. You need to check the output of Wand-config --ldflags --libs. In my case it gave:
$ Wand-config --ldflags --libs
/usr/local/bin/Wand-config: line 50: pkg-config: command not found
/usr/local/bin/Wand-config: line 53: pkg-config: command not found
After relinking pkg-config, libpng, and libfreetype, that became:
$ Wand-config --ldflags --libs
-L/usr/local/Cellar/imagemagick/6.8.8-9/lib -lMagickWand-6.Q16 -lMagickCore-6.Q16
-L/usr/local/Cellar/imagemagick/6.8.8-9/lib -lMagickWand-6.Q16 -lMagickCore-6.Q16
And then:

Package MagickCore was not found in the pkg-config search path.
Perhaps you should add the directory containing `MagickCore.pc'
then:
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
in my .bashrc file to pick up MagickCore.pc, then created two symlinks:
ln -s /usr/local/include/ImageMagick/wand /usr/local/include/ImageMagick-6/wand
ln -s /usr/local/include/ImageMagick/magick /usr/local/include/ImageMagick-6/magick
Now:
$ gem install rmagick

boom everything works fine.
At arch linux, after installing imagemagick#6, gem wasn't able to install package rmagick and got error below.
Can't install RMagick 2.16.0. Can't find MagickWand.h
Worked for me using below steps
added pkgconfig path to .bashrc
export PKG_CONFIG_PATH="/usr/lib/imagemagick6/pkgconfig"
Created two symlinks as below
ln -s /usr/include/ImageMagick-6/wand /usr/include/ImageMagick-6/wand
ln -s /usr/local/include/ImageMagick/magick /usr/include/ImageMagick-6/magick
There are some variants to this problem. Mostly the case is dealing with a legacy application that run older versions of ruby.
rmagick has a dependancy on imagemagick... but not just any. If you've gone too far ahead, it may be wise to backtrack:
brew uninstall imagemagick
Then proceed with an appropriate version
brew install imagemagick#6
then you path needs to be adjusted and forced upon homebrew
export PATH="/usr/local/opt/imagemagick#6/bin:$PATH"
brew link --force imagemagick#6
then you can install rmagick to most recent or versioned
gem install rmagick -v '2.15.4' --source 'https://rubygems.org/'
I had a hard time getting this same issue to work when I had a default ImageMagick install on OSX 10.8 (no homebrew or macports). No combination of the suggestions in this thread or threads linked to from this thread worked for me (modifying the paths for my local install of course).
I simply deleted the default ImageMagick 6 install, and then reinstalled with macports. My rmagick install worked immediately after with no other changes.
on OSX Maverick 10.9.1
it took me ages to figure it out but I solved these issues the following way:
nano /etc/paths
changed:
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
into:
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
that that local stuff, like 'brew' is loaded first.
now I hit 'brew doctor' into the terminal, to see if there's something messed up
if you get the following output
Your system is ready to brew.
everthing is fine. if not ti will tell you what to do. Like kick out unbrewed stuff, broken libs, clean symlinks and whatnot.
When you are ready to brew, you need ghostscript(for pdfs), libpng, imagemagick via brew.
then you can happily type : 'gem install rmagick', in case you did't kill your ruby setup. But thats easy to reinstall via your cleaned up brew.
PS:
another helpful command is: 'which convert', to show you what version of imagemagick is used by the system.
as well as --version
so if you installed git via brew and do 'git --version' and it returns some apple git version, your load path is broken...
On Mac OS X 10.9, try to update your Xcode if there's a warning about it.
$ brew doctor
I you found some warning, do:
$ sudo /Developer/Library/uninstall-developer-folder
Then try:
$ bundle install
again
That worked fine for me.
On CentOS 6.5 x64, it was pretty easy:
yum install ImageMagick ImageMagick-devel
gem install rmagick -v '2.13.2'
I was able to fix this by upgrading to 2.13.2
All brew options failed to install rmagick 2.13.1 on yosemite 10.10
this worked
get the latest RVM
\curl -sSL https://get.rvm.io | bash -s stable --ruby
rvm install 2.1.1
rvm use 2.1.1
download and install the package file
http://cactuslab.com/imagemagick
(I used pacifist to install)
Confirm location of MagickCore.pc file
mdfind magickcore.pc
eg. /opt/ImageMagick/lib/pkgconfig/MagickCore.pc
Manually download rmagick-2.15.2.gem file
https://rubygems.org/gems/rmagick/versions/2.15.2
from that dir
sudo C_INCLUDE_PATH=/opt/ImageMagick/include/ImageMagick-6/ PKG_CONFIG_PATH=/opt/ImageMagick/lib/pkgconfig gem install --local rmagick-2.15.2.gem
If you are having issues with bundle installer still complaining about 2.13.1
In your gem file / gem.lock file upgrade ALL dependencies
rmagick (2.13.1) - > rmagick (>= 2.15.2)
Got same error for alpine 3.9 image build. It comes with ImageMagick 7.0.8.38-r0
To fix that you either use alpine 3.5 with ImageMagick 6.9.6.8-r1:
FROM alpine:3.5
Or install ImageMagick 6.9.6.8-r1 with package repository for 3.5:
RUN apk add imagemagick-dev=6.9.6.8-r1 --repository http://dl-3.alpinelinux.org/alpine/v3.5/main/
There is an open issue in rmagick repo regarding failed builds for ImageMagick 7.0.x. so hopefully it will be fixed soon.
