在执行第3版Ruby on Rails教程的第7章时，我无法让我的rake测试运行Green。

受影响文件的代码如下。

如果有人能够解释我的错误，我将不胜感激

根据Isaffie的建议，问题在于路线文件。

此时文件应如下所示。

Rails.application.routes.draw do
  root             'static_pages#home'
  get 'help'    => 'static_pages#help'
  get 'about'   => 'static_pages#about'
  get 'contact' => 'static_pages#contact'
  get 'signup'  => 'users#new'
  resources :users
end

答案 1 :(得分：0)

检查你的routes.rb文件 - 使用＆＃39; rake routes＆＃39;看看你是否能看到users_path
