Ruby Question

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.

You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/

open new terminal and validate environment is clean from old RVM settings (should be no output):

env | grep rvm

if there was output, try to open new terminal, if it does not help then restart your computer.

install RVM:

\curl -L | 
  bash -s stable --ruby --autolibs=enable --auto-dotfiles

If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04, which gives a bit more explanation.
