我在生产 Rails 站点上收到 500 内部服务器错误,这就是我在 logs/production.log 上看到的。令人惊讶的是,代码在开发中的本地服务器上工作

Completed 500 Internal Server Error in 11745ms

ActionView::Template::Error (undefined method `[]' for nil:NilClass
  (in /home/jason/public_html/site/app/assets/stylesheets/application.css)):
    8:     
    9:     <%= csrf_meta_tags %>
    10: 
    11:     <%= stylesheet_link_tag "application", :media => "all" %>
    12:  
    13:   </head>
    14:   <body>
  app/views/layouts/application.html.erb:11:in `_app_views_layouts_application_html_erb__243082314235891573_4889460'
  app/controllers/main_controller.rb:18:in `index'

我在这里有点迷路,有什么帮助吗?

这是Application.css

 /* You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 *= require_tree .
 *= require_self
 */

/* Main Body */

body {
    background: #f3f3f3;
}

推送到生产环境时需要预编译资产

bundle exec rake assets:precompile

另外,阅读一些资产管道文档,值得您花时间

对于像我这样的人,他们在发生类似错误后最终来到这里,但没有堆栈跟踪:gembetter_errors为我提供了解决问题的信息。
