How to install Rails 3 master from GitHub

Question

I\'m using rvm (Ruby Version Manager) and running Rails 3 RC. I need to test an app to see if a bug has been resolved with a recent commit to Rails 3 master on GitHub.

You can create an empty folder, then put a Gemfile inside, with this:

source 'http://rubygems.org'
gem 'rails', :git => 'git://github.com/rails/rails.git'

Then inside the folder, run:

bundle install

Inside the folder again, run:

bundle exec rails new /path/to_my_new_application/appname

And that's it.
