Question

I’m trying to uninstall Rails completely, but I can’t get the grip of it.

Here’s what I tried:

$ gem update
rails 4.0.0.beta1 instal         


        

Answer 1

in case someone else gets here, i found i had to uninstall railties also.

Check all the directories you might have installed rails in, from your /~user down
