I’m using ember rails on one of my projects. Its a great way to build a ember.js based application with a Rails back-end.
This morning I was trying to deploy to my efforts to Heroku but was running into the following error message:
Running: rake assets:precompile
couldn’t find file ‘handlebars’
Turns out the problem is because I hadn’t specified the ember variant. So if you run into something similar make sure that your development.rb file contains:
config.ember.variant = :development
And your production.rb files contains:
config.ember.variant = :production
