Who told you to run ruby helloworlds_conteoller.rb and why would you expect that output from executing that as a ruby script?
In short, that's just not how Rails is built. Your webserver starts up the entire Rails app -- including loading all associated files and dependencies -- when you run rails server. (which is sounds like you already are successfully able to do?) Running any individual file with the ruby command isn't how a Rails app works.
