Error using ember-rails gem: "Uncaught Error: statement failed: Ember Handlebars requires Handlebars 1.0.beta.5 or higher"

I am using Ember JS for the first time. It is used in a Rails project, and I am using ember-rails stone. I followed the instructions on ember-rails github.

After bundle install I ran rails g ember:bootstrap to disable it. Then I also add the following two lines to application.js:

 //= require ember App = Ember.Application.create();

The problem is that when I visit localhost: 3000 /, I get the following JavaScript errors registered on the console:

 Uncaught Error: assertion failed: Ember Handlebars requires Handlebars 1.0.beta.5 or greater :3000/assets/ember.js?body=1:43 Uncaught ReferenceError: DS is not defined :3000/assets/store.js?body=1:1 Uncaught TypeError: Cannot call method 'template' of undefined :3000/assets/templates/application.js?body=1:1 Uncaught TypeError: Cannot call method 'template' of undefined :3000/assets/templates/application.js?body=1:1 Uncaught Error: <HotDoc.ApplicationView:ember138> - Unable to find template "application".

I am running Rails 3.2.6.

Any ideas how I can solve these problems? As far as I understand, ember-rails includes Handlebars code, so I don't need to add any other gems.

Did I miss something?

In Ember 1.0.pre, they split Handlebars. You must provide it yourself. The embers seem to be taking the same thing.

Edit

You need to add to the beginning of the file

 //= require handlebars
