的Ruby on Rails应用程序不是在生产模式下启动

问题描述：

一切都在发展模式下工作正常，但是当我尝试启动我的生产模式（RAILS_ENV =制作脚本/服务器），我收到以下错误应用：的Ruby on Rails应用程序不是在生产模式下启动

/opt/ruby1.8/lib/ruby/gems/1.8/gems/searchlogic-2.4.19/lib/searchlogic/named_scopes/conditions.rb:81:in `method_missing': protected method `scope' called for #<Class:0x7f41de524410> (NoMethodError)

     from /opt/ruby1.8/lib/ruby/gems/1.8/gems/will_paginate-2.3.12/lib/will_paginate/finder.rb:170:in `method_missing'       
     from /opt/ruby1.8/lib/ruby/gems/1.8/gems/acts_as_commentable-3.0.0/lib/comment_methods.rb:12:in `included'         
     from .../app/models/comment.rb:2:in `include'               
     from .../app/models/comment.rb:2

现在在我看来，acts_as_commentable宝石正在造成这种情况。但是如何来，它在开发模式下运行良好。

show comment.rb（在第2行左右） – fl00r 2010-05-12 17:40:30

答

我发现错误感谢fl00r的评论：

show comment.rb (around line 2)

2号线在comment.rb是include ActsAsCommentable::Comment。这对我来说似乎有点奇怪，所以我看了一下acts_as_commentable gem的官方文档。这是问题所在。它应该是acts_as_commentable。必须从某处复制粘贴它。

尽管如此，它仍然可以在开发模式下工作。由于annaswim提到的类缓存？

答

在开发模式下，类会在您需要时加载。在生产中，它们在导轨启动时被缓存。
