Where is the gem ember-dev?

Question

Digging around emberjs git repo, I found the file config.ru, which contains the line require 'ember-dev'. I started rackup without any errors, but when I then tried irb -rember-dev , I got a load error.

Answer 1

Ember-dev is a repository hosted on GitHub. Try to start irb in the bundler environment

bundle exec irb -r ember-dev
