how to uninstall ruby

Question

How do I uninstall my system installed ruby?

I am on ubuntu 11.1. I have already installed rvm, but it seems 1.8 is conflicting. How do I remove the existing ruby installation and cleanly install ruby back ?

Thanks, Murtaza

I uninstalled ruby, and installed it back through rvm. However when I do 'gem install xxx' it still goes to the dir on file system and not under rvm. How do I remedy it? – murtaza52 Jul 05 '12 at 08:48
