Question

通过了一些解决方案，并在我的development.rb文件

中包含了以下内容

config.assets.precompile = true  
config.assets.precompile =  ['*.js', '*.css', '*.css.erb']

仍面临同样的问题。有人可以帮忙吗？

以下是application.css文件

的快照

/*
 *= require_tree .
 *= require_self
 */

我正在尝试加载内容为

的register.html.erb中的css

<h1>Register#register</h1>
<p>Find me in app/views/register/register.html.erb</p>

我尝试加载的样式表是style_pub.css

h1 {
  color : green;
}

控制台日志错误：

Started GET "/stylesheets/assets/stylesheets/application.css" for ::1 at 2016-08-06 17:17:43 +0530

application.html.erb档案：

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

<%= yield %>

</body>
</html>

建议更改后的新错误日志：

Answer 1

将您的css文件从public目录移至app/assets/stylesheets/目录，它将解决您的问题。

*= require_tree .中的application.css代码行包含css目录中的所有app/assets/stylesheets/个文件。

替换下面的行从

<%= stylesheet_link_tag    'assets/stylesheets/application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'assets/javascripts/application', 'data-turbolinks-track' => true %>

到

<%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>

它会正常工作

Answer 2

这一定对您有用

请将样式表添加到app / assets / stylesheet文件夹中的application.css文件。

/*
*= require style_pub
*= require_tree .
*= require_self
*/

现在尝试重新启动服务器，如果仍然无法正常工作。
