RoR installation on Ubuntu 14.04


  1. sudo apt-get install rbenv
  2. rbenv install [Ruby version]
    This step takes a while...It took 5 minutes on my i7 machine
  3. add system variable to your startup script
    ~/.bashrc in Ubuntu
    add these two lines
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"


That's it. Easier than I expected....
