"Error: ENOENT: no such file or directory" on Ember CLI Mirage - ember.js

Question

I'm an extreme beginner. I'm trying to use Mirage based on the guides shown on the ember website. All my code is more or less the same as in their guide. However, when I go to localhost, I get a Build Error and the following:
dateisrael/mirage/config.js (in /Users/aarontaylor/dateisrael/tmp/babel-input_base_path-B9ZXdbHw.tmp/0)
The Broccoli Plugin: [Babel] failed with:

I tried ember generate ember-cli-mirage again after it didn't work but this didn't help.
What can I do to fix this?
Thanks
