ruby-on-rails - Rails 3.1 Asset Pipeline 对我不起作用

Question

我正在将一个 Rails 2.5 应用程序升级到 Rails 3.1 rc4，我在开发中遇到了大量与 Assets 管道相关的此类错误:

cache: [GET /assets/application-272985f6b5b17a3aeb1b84a6a376e225.css] miss, store
2011-07-06 16:03:56 +0300: Read error: #<NoMethodError: You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each>
gems/ruby-1.9.2-p0/gems/rack-1.3.0/lib/rack/handler/mongrel.rb:90:in `process'
gems/ruby-1.9.2-p0/gems/mongrel-1.2.0.pre2/lib/mongrel.rb:165:in `block in process_client'
gems/ruby-1.9.2-p0/gems/mongrel-1.2.0.pre2/lib/mongrel.rb:164:in `each'
gems/ruby-1.9.2-p0/gems/mongrel-1.2.0.pre2/lib/mongrel.rb:164:in `process_client'
gems/ruby-1.9.2-p0/gems/mongrel-1.2.0.pre2/lib/mongrel.rb:291:in `block (2 levels) in run'

基本上在这里，对 application.css 的请求返回一个空主体。

起初我认为这可能是服务器问题，所以我切换到 webrick，但没有帮助。

非常感谢您的帮助。 ;-)
