Cannot update ruby version

I've just started learning RoR and I've come across a problem.

ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

But when I try to install version 1.9.3 this is what happens:

rvm install 1.9.3
Already installed ruby-1.9.3-p484.
To reinstall use:

rvm reinstall ruby-1.9.3-p484

Sorry if it's a noob question, I've just started learning. I'm running Elementary OS (Ubuntu based distro)

Ruby 1.9.3 is already installed. To use it, write

rvm use 1.9.3

To make it the default version, use

rvm --default use 1.9.3

And to get all your ruby versions installed, use

rvm list

Make ruby 1.9.3 default, or even better use ruby 2.1 if you are just starting with Rails 4.2

 rvm --default use 1.9.3

or better 

rvm install 2.1
rvm --default use 2.1

Since RVM performs non-standard installs, the new version won't be automatically chosen. You have to explicitely "enter" the new Ruby environment with rvm use 1.9.3
