[ruby] Installed Ruby 1.9.3 with RVM but command line doesn't show ruby -v

Here's the console output:

sergio@sergio-VirtualBox:~$ rvm list

rvm rubies

   ruby-1.9.3 [ i386 ]

sergio@sergio-VirtualBox:~$ rvm use 1.9.3
Using /usr/share/ruby-rvm/gems/ruby-1.9.3

sergio@sergio-VirtualBox:~$ ruby -v
The program 'ruby' can be found in the following packages:
 * ruby1.8
 * ruby1.9.1
Try: sudo apt-get install <selected package>

So what's going on? Do I need to reboot my machine? Or should it work right off the bat? I'm using Ubuntu 11.10, any help is appreciated.

I ran into a similar issue today - my ruby version didn't match my rvm installs.

> ruby -v
ruby 2.0.0p481

> rvm list
rvm rubies
   ruby-2.1.2 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]
   ruby-2.2.3 [ x86_64 ]

Also, rvm current failed.

> rvm current
Warning! PATH is not properly set up, '/Users/randallreed/.rvm/gems/ruby-2.2.1/bin' is not at first place...

The error message recommended this useful command, which resolved the issue for me:

> rvm get stable --auto-dotfiles

• Open Terminal.
• Go to Edit -> Profile Preferences.
• Select the Title & command Tab in the window opened.
• Mark the checkbox Run command as login shell.
• close the window and restart the Terminal.
