+If ember throws errors about highcharts, remove highcharts from package.json and reinstall:
 
-* [ember.js](http://emberjs.com/)
-* [ember-cli](http://www.ember-cli.com/)
-* Development Browser Extensions
-  * [ember inspector for chrome](https://chrome.google.com/webstore/detail/ember-inspector/bmdblncegkenkacieihfhpjfppoconhi)
-  * [ember inspector for firefox](https://addons.mozilla.org/en-US/firefox/addon/ember-inspector/)

+it seems that ember install does more than just installing dependencies.
