The easiest way to get Ruby running is to use RVM.
Ruby via RVM
Installation
Install RVM. Their installer script requires package signatures to match so importing their key is required.
# curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
# curl -L get.rvm.io | bash -s stable
... or if you want ruby:
# curl -L get.rvm.io | bash -s stable --ruby
Depending if the installer was executed as a super user, RVM will be installed to:
| User | RVM Location | Profile Script |
|---|---|---|
| root | /usr/local/rvm
|
/etc/profile.d/rvm.sh
|
| user | ~/.rvm
|
~/.rvm/scripts/rvm (don't invoke, source the file)
|
Source the profile script in order to include RVM into the path. Otherwise, execute the rvm script manually.
Install the desired version of ruby. If you are not running this as root, the script will attempt to install them via sudo. The Ruby dependencies I needed were installed with:
# yum install gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel sqlite-devel
# rvm install 2.2.3
Usage
As a normal user, source the profile script and use gem/ruby as you normally would.
Custom ruby gems will be installed in ~/ruby/gems. You may need to define the gems path manually by running GEM_PATH=$GEM_PATH:$HOME/ruby/gems
