[edit] RubyGems

RubyGems is the standard Ruby package manager. It's similar to apt-get, emerge, and other OS package managers.

• Download and Install RubyGems

[~]# cd /root
[~]# cd mkdir source
[~]# cd source
[~]# wget http://rubyforge.org/frs/download.php/35283/rubygems-1.1.1.tgz
[~]# tar xzvf rubygems-1.1.1.tgz
[~]# cd rubygems-1.1.1
[~]# ruby setup.rb

Receive an Error output?

./lib/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- rdoc/rdoc (LoadError) from ./lib/rubygems/custom_require.rb:27:in `require' from setup.rb:23

• Check to see that you have all the libraries needed by rubygems/builder. Missing libzlib-ruby or libyaml-ruby in particular can cause this error. You may also need to install libdrb-ruby, liberb-ruby and rdoc.

Example:

[~]# yum install rdoc

With RubyGems loaded, you can install all of Rails and its dependencies through the command line:

[~]# gem install rails --include-dependencies
[~]# gem list --local
