Error running rails generate devise User

Hey I am new to rails and I am getting this error whenever I try to run

I have looked in the routes.rb file and could not see anything apparently wrong. When I comment out the line:

devise_for :installs

I can run the server again. Any thoughts why this would happen?

I found this error after migrating from Active Record to MongoID, the problem is that the Devise initializer (config/initializers/devise.rb) specifies the ORM (line 25 for me):

require 'devise/orm/active_record'

I just only needed to replace this line with:

require 'devise/orm/mongoid'

Now is working :)

Firstly, why do you use ruby 1.9.3 instead of 2.0 ? Secondly, why do you use rails 4.0.0.rc2 instead of its stable release 4.0 ?

For your question,

devise requires devise_for :users in your routes.rb file. It must be same as your resource name. Use user both in routes.rb and at your generator.
