Uncaught Error: Could not find module ember-cli-tooltipster/components/tool-tipster

I just installed http://ift.tt/19Xpuqt on my ember cli app.

$ npm install ember-cli-tooltipster --save-dev

$ ember g ember-cli-tooltipster

however when I load the rmber app on the browser i get the following error from loader.js

loader.js:58 Uncaught Error: Could not find module ember-cli-tooltipster/components/tool-tipster

Any idea on why I am getting this error ?
