Although its too late to answer this question, but still for those guys who came here to see the solution of same problem just like me and didn't get a satisfactory answer on this page, The reason is that you don't have your file in the form of .rb extension. You most probably have it in simple text mode. Let me elaborate. Binding up the whole solution on the page, here you go (assuming you filename is abc.rb or at least you created abc):

Type in terminal window:

cd ~/to/the/program/location
ruby abc.rb

and you are done

If the following error occurs

ruby: No such file or directory -- abc.rb (LoadError)

Then go to the directory in which you have the abc file, rename it as abc.rb Close gedit and reopen the file abc.rb. Apply the same set of commands and success!
