Question

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.

Answer 1

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/rvm.sh

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 https://get.rvm.io | 
  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.
