I'm getting a SyntaxError when trying to run the ember CLI command

So I recently installed Ember and I was using the Getting Started guide on their site to work on a tutorial project, but unfortunately, when I tried to run the ember command, it threw this strange error. I have attached the image of the SyntaxError.

I have searched everywhere, but I couldn't find an answer to help resolve my issue. Can anyone help me out on how I can get this to work?

Thank you.
