javascript_include_tag throws unsupported method

I recently created a new project with Rails 4.2.0 and created a controller called

for the landing page. So, I ran into this error upon visting

Started GET "/" for ::1 at 2015-02-27 15:56:23 -0600

Is there a way of getting rid of this error? Or is it a bug?


I recently found another solution for this problem. gem 'coffee-script-source' in 1.9.0 has some issues with Rails on Windows. I reverted to the previous version using gem 'coffee-script-source', '1.8.0' in the Gemfile, this will resolve your problem.

Another way of solving this exception is installing Node.js onto your machine and the error should go away after restarting rails server.
