/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2) Install rbenv

First install rbenv using home brew.

brew update

Now you can run the command rbenv init, this will tell you need to add a command to your .bash_profile, you can find this in this repository.

rbenv setup:

You may also need to install git using brew or autocompletion may not work. Install it with:

Don't forget to restart your terminal so changes takes place.
