Question

我遇到了在新的rails应用程序中设置设计的问题。我刚刚创建了一个新的Rails应用程序，添加了设计宝石并运行bundle install。现在，当我尝试运行rails generate devise:install时，我收到此错误：

/Users/Bobo/.rvm/gems/ruby-2.2.4/gems/actionpack-4.2.3/lib/action_dispatch/routing/route_set.rb:557:in `add_route': Invalid route name, already in use: 'new_user_session' 
You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming.

我很困惑，我还没有触及我的路线文件，当我运行rake:routes时它说：You don't have any routes defined!

为什么我收到此错误？这实际上是我采取的第一步..

编辑：我的路线文件

Rails.application.routes.draw do
  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  # root 'welcome#index'

  # Example of regular route:
  #   get 'products/:id' => 'catalog#view'

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

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

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

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

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

  # Example resource route with concerns:
  #   concern :toggleable do
  #     post 'toggle'
  #   end
  #   resources :posts, concerns: :toggleable
  #   resources :photos, concerns: :toggleable

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

Answer 1

您没有定义任何路线，它们都被注释掉了。取消注释根路由，例如变化

  # root 'welcome#index'

  root 'welcome#index'

Answer 2

我在新目录中进行了全新安装，没有其他问题。

Answer 3

更改路线。如上所述，设置 root 确保您有一个名为 WELCOME 的控制器，其中包含模板和操作＆＃39; index＆＃39; 然后root =＆gt; welcome #index将指向该操作。

运行

rails generate devise:install

运行

rails g devise Model

这会自动将您的Model的路线添加到routes.rb文件

使用rails5 rake db:migrate运行rails db:migrate或比你用Devise创建一个Model。
