What happens when you type “irb” (no quotes) at the shell prompt?

You don’t have the interactive Ruby shell installed which script/console  
uses. You probably are using a Debian-based install which annoyingly  
splits Ruby up into a bazillion components that you have to install  
separately if you want everything (okay it’s more like 5 or 6 but  
still).

If you are using a Debian-based Linux box try:

sudo apt-get install irb

and see if that installs it.

If you are using something else you’ll either need to use that  
platform’s package manager to install it or install Ruby from its  
sources.

The OP indicated he was using ubuntu which is, of course debian based.

That said, I long ago gave up trying to use debian packaged versions  
of Ruby. It’s not just that they break it up into pieces, but that  
they twist gems support to fit the debian interpretation of the FHS.

On Debian systems, if you’re serious about Ruby and/or Rails you’re  
much better off installing Ruby and gem from source, and installing it  
to /usr/local
