Question

I am a ruby novice.I created my first ruby on rails application which named "HelloRubyWeb" on my mac.Then "cd HelloRuby",But when I input the command "rails s" ,it returned the error log:

 /Library/Ruby/Gems/1.8/gems/bundler-1.1.5/lib/bundler/runtime.rb:74:in `require': no such file to load -- coffee/rails (LoadError)

Answer 1

kasperite is probably right, in the terminal run:

bundle then run rails s

Post the errors you get if any.

Answer 2

I had the same issue, but in my case it was because of the explicit coffee-rails version.

1) remove strictly set version for coffee-rails gem in Gemfile

2) run bin/bundle

3) run bin/bundle update

4) run bin/rails s

If you need explicitly set working version, just run bin/bundle show 'coffee-rails' and copy the version number from the terminal.
