我是使用 Rails 的新手。我正在关注 Treehouse“构建一个简单的 Ruby on Rails 应用程序”教程。直到现在一切都很好。

我正在尝试生成设计视图，但是当我转到 localhost:3000/users/sign_up 时，我收到一条错误消息

Routing Error

No route matches [GET] "/"
Try running rake routes for more information on available routes.

当我转到 users/sign_up、users/sign_in 时会发生这种情况，但当我转到 users/edit 时不会发生这种情况

当我尝试访问 users/sign_up 时，终端向我吐口水

当我运行 rake 路线时，这就是它的样子

    Mikes-MacBook-Pro:treebook mike$ rake routes
    new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
        user_session POST   /users/sign_in(.:format)       devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format)      devise/sessions#destroy
       user_password POST   /users/password(.:format)      devise/passwords#create
   new_user_password GET    /users/password/new(.:format)  devise/passwords#new
  edit_user_password GET    /users/password/edit(.:format) devise/passwords#edit
                     PUT    /users/password(.:format)      devise/passwords#update
cancel_user_registration GET    /users/cancel(.:format)          devise/registrations#cancel
   user_registration POST   /users(.:format)               devise/registrations#create
new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new
  edit_user_registration GET    /users/edit(.:format)          devise/registrations#edit
                     PUT    /users(.:format)               devise/registrations#update
                     DELETE /users(.:format)               devise/registrations#destroy
            statuses GET    /statuses(.:format)            statuses#index
                     POST   /statuses(.:format)            statuses#create
          new_status GET    /statuses/new(.:format)        statuses#new
         edit_status GET    /statuses/:id/edit(.:format)   statuses#edit
              status GET    /statuses/:id(.:format)        statuses#show
                     PUT    /statuses/:id(.:format)        statuses#update
                     DELETE /statuses/:id(.:format)        statuses#destroy

我很困惑下一步该做什么。任何帮助都非常感谢！

谢谢

您需要定义一个根路径，以便 Rails 在某人打开根路径时知道将其发送到哪里。

http://guides.rubyonrails.org/routing.html#using-root

一旦您登录，设计将希望重定向到某个地方，并且没有根路由，它无处可去。

root to: "statuses#index"可能是一个不错的起点

Rails 找不到你的root_url.

尝试将以下内容添加到您的routes.rb并重新启动您的服务器。

root to: '/'

root路由器的辅助方法在哪里to: 'controller#action'从您的一个控制器中获取选项哈希，例如users#index.

的值to可以采用字符串或其他 ruby​​ 对象，您将学习到！
