“Ruby on Rails-教程”期间的路由错误

似乎这里有些人遇到了这个问题，但我在另一个主题中找不到任何解决方案。

我正在学习 Ruby on Rails 教程的第 3 章，处理静态页面。当我想在本地主机上打开它们时，它会在浏览器中显示“路由错误”。

我的 Ruby 目前版本为 1.9.3。 My Rails 目前版本为 3.2。

我努力了：

• 重新启动服务器
• 再次保存所有文件
• 检查 static_pages_controller.rb 中的任何问题
• 检查routes.rb中的任何问题
• 检查 static_oages_spec.rb 中的任何问题

单个静态页面的 HTML 代码也没有错误。我在教程中找不到更多帮助，在 StackOverflow 上的其他问题中也找不到任何帮助。

Edit:

这是来自浏览器的实际错误消息：

路由错误

没有路由匹配 [GET] "/static_pages/home" 尝试运行 rake 路线以获取有关可用路线的更多信息。

如果我去http://localhost:3000/static_pages/home，到我拥有的三个静态页面之一。

这是routes.rb：

SampleApp::Application.routes.draw do
  
get "static_pages/home"

get "static_pages/help"

get "static_pages/about"

end

另外，我尝试过“rake routes” 也在终端中。这是结果：

home_static_pages GET    /static_pages/home(.:format)  static_pages#home
 help_static_pages GET    /static_pages/help(.:format)  static_pages#help
about_static_pages GET    /static_pages/about(.:format) static_pages#about
      static_pages POST   /static_pages(.:format)       static_pages#create
  new_static_pages GET    /static_pages/new(.:format)   static_pages#new
 edit_static_pages GET    /static_pages/edit(.:format)  static_pages#edit
                   GET    /static_pages(.:format)       static_pages#show
                   PUT    /static_pages(.:format)       static_pages#update
                   DELETE /static_pages(.:format)       static_pages#destroy

这是服务器给我的错误消息：

尝试这个 ：

match "/static_pages/home" => "static_pages#home", :via => :get
match "/static_pages/help" => "static_pages#help", :via => :get
match "/static_pages/about" => "static_pages#about", :via => :get

添加到路由中，重新启动服务器并刷新浏览器。
