I'm having trouble getting the application to work on Chapter 1 Step 5. I've even tried copying the downloaded sample code over my working code and I still receive the same message.

ReferenceError: _ is not defined
at WatchlistService.loadModel (watchlist-service.js:58)
at new WatchlistService (watchlist-service.js:107)
at invoke (angular.js:3967)
at Object.instantiate (angular.js:3978)

at getService (angular.js:3931)
at invoke (angular.js:3958)
at Object.instantiate (angular.js:3978)(anonymous function) @ angular.js:10147

There is also a reference error, but I do not know if it is related or not:

Failed to load resource: the server responded with a status of 404 (Not Found)

http:// localhost:9000/bower_components/ lodash/dist/lodash.compat.js

Any help would be appreciated. This entire chapter has been one misstep after the next for me.

Edit: this forum insisted on shortening my url for me so the spaces there are intentional

did you run bower install in that folder?

the error tells you lodash is missing.

Looks like adding

<script src="bower_components/lodash/lodash.js"></script>

to the index.html file solved the functionality problem but the error still appears in the console.
