Why does Ruby throw an error when running a file?

Question

Ruby on Rails

Why does Ruby throw an error when running a file? Installed RailsInstaller. Everything was fine before. Plus, I give this file permission rb, and he sees it as a notepad
. What's the problem?

Answer 1

First, there should be no spaces in the file name. Rather, you should have an error like there is no such hello file or directory. Since you are trying to run the hello file and pass the world.rb argument to it.
Secondly, you have some nonsense with the rubegms gem. Have you installed Ruby correctly?
Or are you trying to include rubygems in code?
