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 并且仅对 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 gem（例如 mysql2 gem 等）的问题。但直到现在我已经解决了所有问题。现在我处于这种情况，当我有应用程序时，当我在 localhost 上测试它时，我在 Web 浏览器中得到了这个错误：

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

Webrick 日志：

每次单击某些链接时都会显示此错误

这是我的系统属性：

  1. 视窗 7 x86
  2. 红宝石/1.8.7/2011-02-10
  3. WEBrick/1.3.1
  4. 导轨 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：（我认为它可能在路线中......我很抱歉这个愚蠢的问题，我是新手......

开发日志：很奇怪，因为服务器日志看起来像这样：

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。我会看看它的进展如何......
