I installed ruby via rvm into Ubuntu 12.04 lts. In terminal when I type ruby -v to check what version of ruby im on it list 1.8.7. Problem is I never installed this version and when I type rvm list, it says my default and current ruby version is 2.0.0 and is the only ruby version listed as which is the only version I have installed. What could be causing ruby -v command to list say that I'm on a different version and which version am I really on?
