It sounds like your 1.9.3 install might be in front of your rbenv / rvm Rubies in your system PATH - this would cause the system to always use the first Ruby command it finds in the path. Try running the following in your command line and see if there are multiple different Ruby installations or references to RVM etc, and swap their order if necessary.

echo $PATH

To make permanent changes to your PATH, its best to look up how to do so for your operating system - it's usually a simple matter of adding or modifying a line to a hidden file in your home directory.

Hope that helps.

I suggest to read rvm cheatsheet, like this http://cheat.errtheblog.com/s/rvm

In your case you want to execute

rvm list known

rvm install 2.1 (or any other ruby from list)

rvm use --default 2.1 (it will remember to use 2.1 in future)

I'm currently reading the cheatsheet, but the rvm use --default is still giving me a bit of trouble, but there are alot of goodies on the sheet,thx for sharing ;)

i fixed it guys, with some help of a fellow from twitter, i had to go in the terminal in ubuntu and settings and do the title and command and run command as a login shell [ i had to check that box ] after that it worked like a charm.
