I dont understand why after the rvm command I am still on ruby 1.8.7. Ive followed the install instructions for rvm and it all seemed to go fine – where do I look to start resolving this?

andrew@unifex:~$ rvm use 1.9.2 --default
Using /home/andrew/.rvm/gems/ruby-1.9.2-p290
andrew@unifex:~$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]
andrew@unifex:~$

andrew@unifex:~$ rvm info

ruby-1.9.2-p290:

    I had this exact problem. It’s down to your $PATH not being correct – /usr/bin/ruby is found before rvm gets a chance to do its thing.

    In your ~/.bash_profile (As in /Users/andrew/.bash_profile) ensure you have this line present at the bottom of the file:

    [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

    Then open a new shell

    rvm reload
rvm use 1.9.2 --default
ruby -v

    You should now have the correct version displayed.
