Ruby on mac - requires don't work

Ruby
1

Hi - i’m trying to write a ruby program on my wife’s mac (i use linux
normally). In irb i can require a gem fine, but when i write a little
program, save it on her desktop and run it, the require doesn’t work -
it can’t find it.

I’m sure it’s just some dumb thing i’ve not done or taken into account.
Do ruby scripts need to live somewhere in particular, for example?

You probably are missing this line first:
require ‘rubygems’

If it is a gem that has gone missing try adding:

require ‘rubygems’

before you attempt to require the gem. I’m assuming the gem is
installed in the gem repository and isn’t just sitting in a file in a
working directory somewhere.
