Ember: fa-icon is not a helper

I recently installed the Ember Font Awesome plugin into ember-social-share to make it easy to render icons. It worked for me locally, however now when I add ember-social-share to my application and call it, I get...:

Uncaught Error: Compile Error: fa-icon is not a helper

I've seen a lot of documentation online about how this is an issue people have run into, but I haven't been able to find a solution. Any help is greatly appreciated!
