Why is my development server not loading? default_controller_and_action': missing :action (ArgumentError)

Question

I\'m a Ruby nuby (and new to Stack Overflow) working on the Rails Tutorial by Michael Hartl and all of a sudden my development server won\'t load and keeps exiting. Console

Answer 1

When I ran into this problem, it was because one of the routes in routes.rb had a slash (/) instead of the hash (#) when using the controller#action syntax (I used "controller/action", which was incorrect).

For example, I accidentally had root :to => 'home/index'. It was supposed to be root :to => 'home#index'.

I found this solution in here.
