Where are they installed? Could you run these commands and show the output please. $ ruby -v $ which ruby # if it is a symlink, follow it also $ gem -v $ which gem # if it is a symlink follow it also $ echo $PATH And again ... even if you have started with manual install of Ruby etc, you can still go to rvm (and inside rvm you can use `$ rvm system` to go back to the system installed ruby if you need to; I demonstrate that below).
