Question

我在设置rails应用程序时遇到问题。我们使用rails 3（我们也使用memcached），并安装了everthing（DB，ruby，rubygems，rails，...）并配置了数据库。因此，如果我运行 rails服务器，则应用程序启动正常。

对于制作我们将使用 Apache和Phusion Passenger ，两者都已成功安装。当我重新启动apache时，我收到此错误：

* 首先我认为它可能与memcached有些关系，比如一些缺少apache的模块，但我读到apache / passenger没有配置。

我的问题是，为什么应用程序无法启动？我忘了安装或配置某些东西吗？我真的不知道自从应用程序使用 rails server 启动时可能会有什么损坏。

看看这个文件：

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

自Rails 2.3起，此文件应称为 application_controller.rb ，而不是 application.rb 。重命名文件，它应该工作：

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

undefined局部变量或方法`application_controller'for main：Object
