Using RVM for Gem Management - ParkinT/RubyMotion_Life GitHub Wiki

#colinta would add to this: use rvm to keep your gem installations isolated, and so that you don't have to use sudo when using gem. It will feel very much like brew install ...

1. rvm use 1.9.3 # <= i put this in my .bash_rc
2. rvm gemset use $project # <= I have this run in each project when I cd into that folder for the first time
3. gem install bundler # install bundler
4. bundle # install from Gemfile
