How to replace the handlebars with htmlbars in Ember CLI app?

I am facing the following issue after upgrading the Ember and Ember data to the canary versions.

Cannot set property 'compilerInfo' of undefined

I found the discussion about the issue in Ember CLI repo.

The solution is to replace handlebars with htmlbars. But I don't know the exact steps to do that.

I checked handlebars repo. It gives code snippets but I don't know where to place the code exactly.

Any idea?
