rails generate scaffold error

问题:

I'm working on the RailsTutorial.org book and I keep hitting an error. When I run

rails generate scaffold User name:string email:string 

I'm getting the following error:

/Users/Cody/Development/rails_projects/demo_app/config/environments/development.rb:1:in `<top (required)>': undefined method `configure' for #<DemoApp::Application:0x007fdcea90ae10> (NoMethodError) 

I'm running Ruby 2.0.0 and Rails 4.0.4. Here is the contents of enviroments/development.rb

Rails.application.configure do config.cache_classes = false config.consider_all_requests_local       = true config.action_controller.perform_caching = false config.action_mailer.raise_delivery_errors = false config.active_support.deprecation = :log config.active_record.migration_error = :page_load config.assets.debug = true config.assets.raise_runtime_errors = true end  

Please let me know if you need to see any more of the code snippets. Any help would be greatly appreciated.

try:

   DemoApp::Application.configure do     config.cache_classes = false     config.consider_all_requests_local       = true     config.action_controller.perform_caching = false     config.action_mailer.raise_delivery_errors = false     config.active_support.deprecation = :log     config.active_record.migration_error = :page_load     config.assets.debug = true     config.assets.raise_runtime_errors = true    end
