Question

我是ruby on rails的新手，并开始在一个名为openclassroom的法国网站上学习。所以在说明中它告诉我使用这个命令创建一个html页面：

$ rails g controller pages home #we are launching our webpage
$ rails server #we launch our server

当我尝试访问http://locahost:3000/pages/home时，它会给我一个错误。屏幕看起来像这样......

Link to the image of the error message

以下是app/views/layouts/application.html.erb

目录中的页面

<!DOCTYPE html>
  <html>
    <head>
     <title>Castor</title>
     <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
     <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
     <%= csrf_meta_tags %>
   </head>
   <body>

     <%= yield %>

   </body>
 </html>

这是我的路线文件，可在config/routes.rb

中找到

Rails.application.routes.draw do
   get 'pages/home'
end

这是我的主页app/views/pages/home.html.erb

<h1>Pages#home</h1>
<p>Find me in app/views/pages/home.html.erb</p>

虽然我不认为问题来自这里。这是我的GemFile
