it has to be in your user folder so open a new finder window and you should see your device on the side. Click that then Mackintosh HD then Users then your user. Put the Development file in there.

I suggest you look into this course. You should have a good understanding of how to work in the terminal.

To do this correctly. I would put a Projects folder into your user directory. So let's say that is "Kelvin" on your Mac. Then you open finder, on the toolbar at top, click "Go -> Home". Add your folder here. So the folder now is located at Users/Kelvin/Projects.

When you open a terminal, it automatically brings you to Users/Kelvin. So we use "cd Projects" to change directory to projects. Now we are located at Users/Kelvin/Projects in the terminal and any files stored in this folder can now be run.

You can't have a space in the name of the file. Terminal is trying to run vars.rb instead of ruby vars.rb Replace the space with _ to make it easier to read: ruby_vars.rb

I don't believe he had a space in his file name. Isn't he running the ruby command with the filename "vars.rb"?

The error is indicating that your working directory is not the same directory as where you saved the file.

OK, what you need to do is create a folder, say development under your user. Then type into the terminal cd development Then re-create the file there, then you should be in the directory in the terminal and it should work to run.
