Hello all, I'm a RoR newbie!
I have installed RVM and have Ruby 1.8.7 and 1.9.2 installed.
I am following the steps from the book on RailsTutorial.org and have
gotten tripped up on the Installing Rails section. I installed Rails
using the sudo command as follows:
sudo gem install rails --version 3.0.1
It looked like it installed, however when I typed
rails -v
I got this:
Rose-MBP:~ roseemmons$ rails -v

Good Lord, what did I do wrong?
