Setup Ruby on Rails OS X Lion

In the last 6 months I have installed Ruby on Rails 3 a hand full of time on OS X. There are lots of different articles on how to do this but this is the simplest and the best way I have found to setup my Ruby on Rails 3 development environment.

Install XCode 


Install Hombrew 

Install Git (with homebrew)

  • brew install git 

Install RVM (Ruby version manager) 

Install Ruby 1.9.2 (or whatever version) 

  • rvm install 1.9.2 

Install Rails 3 

  • Rails is a gem, so you can include this in your new Rails projects gem file and have it available. In your .Gemfile it is just 
  • gem 'rails', '3.0.9'
