未定義的局部變量或方法`application_controller'for main：對象

Question

我在設置rails應用程序時遇到問題。我們使用rails 3（我們也使用memcached），並且安裝了everthing（DB，ruby，rubygems，rails，...）並配置了數據庫。因此，如果我運行導軌服務器，則適用開始正常。

對於生產我們將使用Apache和Phusion Passenger，兩者都已經安裝成功。當我重新啓動Apache我得到這個錯誤：

* 首先，我認爲這可能與分佈式緩存進行sometnig，像阿帕奇缺少一些模塊，但我看是沒有必要的配置爲阿帕奇/乘客。

我的問題是，爲什麼應用程序無法啓動？我忘了安裝或配置someting？我真的不知道什麼可能是因爲應用程序啓動確定導軌服務器。

看看這個文件：

/media/Disc/ABC/CODE/TESTINGAPP/app/controllers/application.rb 

因爲Rails的2.3，這個文件應該稱爲application_controller.rb，而不是application.rb中。重命名文件，它應該工作：

/media/Disc/ABC/CODE/TESTINGAPP/app/controllers/application_controller.rb
