error running rails generate devise:install

Question

When running rails generate devise:install I get a below error message. Could you please advise me on where I may have gone wrong? The devise gem seems to have been installed correctly, although there is no devise.rb in initiliazers.

Thank you!

I had a similar issue and add the following to my gem file:

    gem 'devise', :github => 'plataformatec/devise', :branch => 'rails4'

Also check that you don't have any devise scope in your routes I hope this helps you as well.
