Error messages in browser console

Snap shot of my work space*: https://w.trhou.se/h1y56rpv0c

*As you can see I have linked to a later version of ember.js as I had some error messages in my browser console which said too. Then have linked to a CDN of local storage, as clicking the link in the teacher notes I did not know what to download/proceed. Thinking it's change a bit since the tutorial was made.

Red error messages in my console are:

store.js:2 - Uncaught TypeError: DS.LSAdapter.extender is not a function
