I created a new project with name of the controller collections(install the rails 2.3 then update it to 5.1 version, gem install bundler, bundle install, ruby 2.33 ).. I tried to run the collections/index I am getting this error on windows. I do some research regarding to this error, followed all the instructions given
Putting the gem 'coffee-script-source', '1.8.0' into my gem file then bundle update coffee-script-source. I also change the application into default(located at application.html.erb) but when I change it to default it gives me another error "Sprockets::Rails::Helper::AssetNotFound in Collections#testing The asset "default.css" is not present in the asset pipeline."
Question: What should I do to fix this error?
