動作控制器：異常路由錯誤

Question

我的網站應用程序運行時，我推到heroku，但是當我運行本地主機：3000，我得到一個「路由錯誤」「沒有路由匹配」/「。我一直在搜索遍地一個答案，不能找出該怎麼做。我的routes.rb下面列出。謝謝。

Kliqq::Application.routes.draw do 



    get "home/index" 
    get "welcome/index" 

    resources :groups 
    devise_for :admins 
    devise_for :users 


    # The priority is based upon order of creation: 
    # first created -> highest priority. 

    # Sample of regular route: 
    # match 'products/:id' => 'catalog#view' 
    # Keep in mind you can assign values other than :controller and :action 

    # Sample of named route: 
    # match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase 
    # This route can be invoked with purchase_url(:id => product.id) 

    # Sample resource route (maps HTTP verbs to controller actions automatically): 
    # resources :products 

    # Sample resource route with options: 
    # resources :products do 
    #  member do 
    #  get 'short' 
    #  post 'toggle' 
    #  end 
    # 
    #  collection do 
    #  get 'sold' 
    #  end 
    # end 

    # Sample resource route with sub-resources: 
    # resources :products do 
    #  resources :comments, :sales 
    #  resource :seller 
    # end 

    # Sample resource route with more complex sub-resources 
    # resources :products do 
    #  resources :comments 
    #  resources :sales do 
    #  get 'recent', :on => :collection 
    #  end 
    # end 

    # Sample resource route within a namespace: 
    # namespace :admin do 
    #  # Directs /admin/products/* to Admin::ProductsController 
    #  # (app/controllers/admin/products_controller.rb) 
    #  resources :products 
    # end 

    # You can have the root of your site routed with "root" 
    # just remember to delete public/index.html. 

    root :to => "home#index" 

    # See how all your routes lay out with "rake routes" 

    # This is a legacy wild controller route that's not recommended for RESTful applications. 
    # Note: This route will make all actions in every controller accessible via GET requests. 
    # match ':controller(/:action(/:id(.:format)))' 
end 

我現在認識到這個問題是色器件。當現在運行它，我得到「沒有devise_for」的方法。 這裏是我的全部跟蹤

你有沒有在你的Gemfile指定的設計？如果沒有，那會導致「undefined method devise_for」錯誤。
