Rails 3 - 错误 Errno::EINVAL：测试页面时参数无效

Question

嗨， 我需要帮助。我在 Ruby on Rails 3 中开发了应用程序。它的简单应用程序包含一些 scadfolds 和仅对 mysql 数据库进行 CRUD 操作。因为我是 Windows 64 位用户，所以我有时会遇到一些 gems 的问题（例如 mysql2 gem 等）。但到目前为止我已经解决了所有问题。现在我的情况是，当我有应用程序时，并且当我在本地主机上测试它时，我在网络浏览器中收到此错误：

内部服务器错误 无效参数 WEBrick/1.3.1 (Ruby/1.8.7/2011-02-18) at localhost:300

每次单击某些 link_to 时都会显示此错误

这是我的系统属性：

1. Windows 7 x86
2. Ruby/ 1.8.7/2011-02-10
3. WEBrick/1.3.1
4. Rails 3.0.7

我的路线：

resources :priorities
resources :timelines
resources :cathegories
resources :statuses
resources :user_sessions
resources :users
resource :user, :as => 'account'
resources :tasks  
match 'signup' => 'users#new', :as => :signup  
match 'admin' => "application#index",      :as => :admin  
match 'login' => "user_sessions#new",      :as => :login
match 'logout' => "user_sessions#destroy", :as => :logout

root :to => "users#show"

真的不知道错误在哪里:(我认为它可以在路线中... 我对愚蠢的问题感到抱歉，我是新手..

开发日志： 它很奇怪，因为服务器日志如下所示：

好的，我找到了这个问题的解决方案。我决定将我的网络服务器更改为 morgel。经过两个小时的工作，没有出现任何错误。也许这个问题真的取决于我的环境 - Win 64bit/ruby/mysql/rails3 和 webrick。我会看看事情进展如何...
