未初始化的常量ActionController :: Routing（NameError）
我试图在Linux服务器上部署我的应用程序时收到此错误。

您已从较旧的2.x版本的Rails更新此应用程序。 你的config/initializers/new_rails_defaults.rb中有一行使用ActionController::Routing常量，Rails 4.2中不再存在该常量。
所以，基本上，这里的修复是将您的应用程序正确升级到4.2。 我可以告诉你从你的文件中删除ActionController::Routing行，但这可能只是你在这里没有修复的许多其他问题之一。
这里奇怪的是你没有提到在开发中遇到同样的问题，这表明你实际上并没有使用你认为自己的开发版Rails。
祝好运。
