Ruby on Rails Installation

Install Ruby

Use a recent Ruby version. Recent is 1.9.3 atm.

• Debian: ruby1.9.3 (testing repo)
• Arch: ruby
• OS X: brew install ruby
• FreeBSD: lang/ruby19
• etc.

Set Environment Variables

Set a user specific gems dir (because of reasons) and the search path:

 $ mkdir $HOME/.gem
 $ export GEM_HOME=$HOME/.gem
 $ export PATH=$PATH:$HOME/.gem/bin

Remember to make these persistent!

Install Bundler Gem

Use the Bundler gem to manage dependencies for each project:

 $ gem install bundler

Go to the project directory and install specified gems:

 $ cd [PROJECT]
 $ bundle

Or, initialize a new Rails installation with the most recent version:

 $ gem install rails
 $ rails new [PROJECT]
