Fix RVM problem: RVM is not a function, selecting rubies with 'rvm use ...' will not work.

rvm_fix.md

Assumptions:

You have RVM installed using the steps documented in http://www.rvm.io

Steps:

Add the following line to your ~/.bash_profile or ~/.bashrc

source ~/.rvm/scripts/rvm

Then, either open a new terminal window or run

. ~/.bash_profile

Check if everything works

type rvm | head -n 1

If all goes well, you should see the message:

rvm is a function
