I have already install libmemcached using
sudo yum install libmemcached
On Ubuntu, try doing:
sudo apt-get install libsasl2
sudo apt-get install libsasl2-dev
I encountered this issue trying to install the memcached gem on Amazon's AMI Linux.
I resolved it with installing both cyrus-sasl and cyrus-sasl-devel:
cyrus-sasl.i686 : The Cyrus SASL library
cyrus-sasl-devel.i686 : Files needed for developing applications with Cyrus SASL
as well as, and this is key:
gettext.i686 : GNU libraries and utilities for producing multi-lingual messages
gettext-devel.i686 : Development files for gettext
Once these were installed
sudo gem install memcached

I think you need to install memcache-client instead.
gem install memcache-client
and you will see this:

I tried to install a package using RubyGems (please note that I use Windows Subsystem for Linux). I was going to install Jekyll package.
I typed $ gem install jekyll. After that it came up with an error:
Building native extensions. This could take a while...
/usr/lib/ruby/2.5.0/rubygems/ext/builder.rb:76: warning: Insecure world writable dir /mnt/c in PATH, mode 040777
ERROR: Error installing jekyll:

Can you please explain the error and any possible ways to fix it?
You need to install the build tools needed:
sudo apt-get update
sudo apt-get install build-essential
I had to install ruby-full to get this working on WSL:
sudo apt install ruby-full
I did: sudo apt-get install ruby ruby-dev.
And i run: sudo gem install jekyll.
But it gives this output:
Building native extensions. This could take a while... ERROR: Error

You need to install make and other build tools first, run this:
sudo apt-get install build-essential
make: not found
This means that the program make (that is used to build libraries from code) is not present on your machine. You should try to install it with your package manager.
sudo apt-get cmake
might do the trick.
sudo apt-get install build-essential solves the issue for mysql gem failing due to make program failure for linux.
Complete Noob at UBUNTU, but..
I have got an UBUNTU server from backspace and I have installed Ruby 2.0
so ruby -V gives me version 2.0
I am now trying to install Helios with

You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.
You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
the file is libpq-fe.h and it cannot find it, but after searching it says this file is from Postgres and I have followed the ubuntu installation of postgres and i have installed the client and the server.
So I am completely lost.
Try installing libpq-dev PostGre library:
sudo apt-get install libpq-dev
That fixed it for me.
I'm installing the Ruby Nokogiri gem and finding the error below.
How to diagnose this and solve it?
# gem install nokogiri

...
To diagnose and solve, here's what worked for me.
To find out what failed, go to your ruby gems directory.
For example:
$ cd <MY RUBY DIRECTORY>/lib/ruby/gems/2.0.0/gems
If you don't know your gem directory, try this:
$ echo $GEM_HOME
/opt/gems/2.0.0
$ cd /opt/gems/2.0.0/gems
What version of nokogiri am I installing?
$ ls -ladg nokogiri-*
nokogiri-1.5.5
Go to the installer directory:
$ cd nokogiri-1.5.5/ext/nokogiri
Try installing manually:
$ ruby extconf.rb
Result:
checking for libxml/parser.h... *** extconf.rb failed ***
...
I'm using Ubuntu so I search for any similar packages:
$ aptitude search libxml
Results:
p libxml2 - GNOME XML library
p libxml2-dev - Development files for the GNOME XML library
...
I believe that libxml2 will work fine.
$ apt-get install libxml2
Ruby native gems often need the *-dev packages for headers so install them:
$ apt-get install libxml2-dev
Now do I have the parser file?
$ find / | grep libxml/parser.h
Yes, the result shows the parser:
/usr/include/libxml2/libxml/parser.h
Now try installing again, this time providing the libxml2 path:
$ gem install nokogiri -- --with-xml2-dir=/usr/include/libxml2
It still fails, so read the mkmf error log:
$ more mkmf.log
The error log shows what failed and has these lines that look promising:
package configuration for libxslt is not found
Is there a package for it?
$ aptitude search libxslt
Results:
v libxslt-dev
i libxslt-ruby
...
Install the dev package:
$ apt-get install libxslt-dev
Now try installing again, and also put xslt on the path:
$ gem install nokogiri -- \
--with-xml2-dir=/usr/include/libxml2 \
--with-xslt-dir=/usr/include/libxslt
Success!
Installing Nokogiri Website
'Installing Nokogiri' is a website dedicated to installing Nokogiri on the major platforms - Here is an excerpt about Installing Nokogiri on Ubuntu:
Because Nokogiri needs to be compiled and dynamically linked against
both libxml2 and libxslt, it has gained a reputation for being
complicated to install.
As of Nokogiri 1.6, libxml2 and libxslt source code is bundled with
Nokogiri, and compiled at gem-install-time. The instructions in this
document should work for all versions 1.6.4 and later.
Ubuntu / Debian
Installation should Just Work™ on Ubuntu and Debian using Nokogiri’s
vendored libxml2 and libxslt:
gem install nokogiri
[...]
Using Your System Libraries
If, instead of Nokogiri’s vendored libraries, you’d like to use your
system’s libxml2, libxslt and related libraries, please first
understand that you may be asking Nokogiri to work with an unsupported
version of libxml2.
sudo apt-get install pkg-config
gem install nokogiri -- --use-system-libraries
FYI - I am using Nokogiri 1.6.6.2 and it didn't 'just work'. I got it going with the --use-system-libraries.
Mac OS X
The website's advice also covers OS X - this worked for me:
gem update --system
xcode-select --install
gem install nokogiri
Conclusion
If you have a Nokogiri problem on any platform you should check out the website.
On CentOS here is what I needed to do:
gem update --system
yum install libxml2-devel libxslt-devel ruby-devel
gem install nokogiri -- --use-system-libraries
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.
You are probably missing zlib headers which are required for -lz flag in order to compile the sources correctly. Install on Linux by:
sudo apt-get install libz-dev
For missing libiconv, try installing libiconv-hook-dev package which has header files of libiconv-hook, e.g.
sudo apt-get install libiconv-hook1 libiconv-hook-dev
On OS X, try installing development tools via: xcode-select --install.
If there is still problem, check mkmf.log file for more specific details about your error.
On Ubuntu, try the following dependency fix combo:
sudo apt-get install gcc ruby-dev libxslt-dev libxml2-dev zlib1g-dev
The 'could not create Makefile' error you're seeing could also be because you haven't agreed to the Xcode license (you have to agree to it after each time you update Xcode). Running sudo xcodebuild -license accept should eliminate this error for you and allow you to then run gem install nokogiri successfully.
I bought a new Mac this week and have had big problems getting this gem installed. It was never a problem on my old Mac but seems to be particularly difficult on this one.
I have installed libvirt via Homebrew, Xcode4.4 (with command line tools) and gcc4.2. I have symlinked to make gcc4.2 the default compiler.
gem install ruby-libvirt -v '0.4.0' fails because it cannot find the headers
If I pass in the paths to the headers and libraries, like so:
ruby-libvirt -v '0.4.0' -V -- --with-libvirt-include=/usr/local/Cellar/libvirt/0.9.11.3/include/ --with-libvirt-lib=/usr/local/Cellar/libvirt/0.9.11.3/lib/
, it compiles just fine but fails when linking with the following errors:
linking shared-object _libvirt.bundle
ld: library not found for -lruby.1.9.1
collect2: ld returned 1 exit status
make: *** [_libvirt.bundle] Error 1
I have installed Ruby 1.9.3 via RVM and haven't had any troubles installing other native extensions, so I cannot see why it fails to find the ruby libraries in this case.
Does anyone have any ideas? Help would be much appreciated.
I built ruby-libvirt-0.4.0/ext/libvirt by proving external libvirt installed using brew.
Here is what I did to successfully install libvirt.
brew install libvirt
ruby extconf.rb --with-libvirt-include=/usr/local/include/libvirt --with-libvirt-lib=/usr/local/lib/libvirt
gem install ruby-libvirt -v '0.4.0' -V -- --with-libvirt-include=/usr/local/Cellar/libvirt/1.1.4/include/libvirt --with-libvirt-lib=/usr/local/Cellar/libvirt/1.1.4/lib
Hope this helps.
To install the gem you need to install the libvirt libraries. Using 'Homebrew' (a package manager for mac) :
brew install libvirt
bundle install
The exact error you got might have been:
An error occurred while installing ruby-libvirt (0.4.0)
I have finally solved this. It turns out that the command line tools were not properly installed. The following line needs to be added to your .zshrc file (or whatever applies to your choice of shell):
export PATH=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:$PATH
You need only to install libvirt, before the bundle install.
brew install libvirt
