Can anyone point me in the right direction as to whats going wrong?

Im using ember 2.8.0 and using the latest version of ember-cli-mirage.

Please bare in mind I am really new to ember.

Answer 1

Is there a specific reason you are starting with Ember 2.8? Unless there is, I would suggest fully removing Ember-CLI ( npm uninstall -g ember-cli ) and starting over with Ember 3.0.

The reason I suggest that is that the errors you are seeing there look to be due to Babel upgrades that Mirage is expecting in the latest version of Mirage but that don't exist in the older version of Ember that you have installed.
