Rails install and Uninstall

Hi, I'm having troubles with uninstalling rails 4.0.2. After I uninstall completely railties and rails. I type rails --version it shows me "Rails4.0.2" I've also installed an older version of rails. Can someone help me with this issue. (I'd like to see answers of installing older version of rails using rvm. )

This sounds like a pretty common problem folks have when they install multiple different versions of something. With Rails, specifically, you need to designate a gemset to accompany the version of Rails you want to run. Check out this article on StackOverflow for the details. http://stackoverflow.com/questions/18348373/how-to-use-rvm-and-different-versions-of-rails
