Ruby on rails项目：我在服务器（app，config）上升级了我的文件，成功运行了bundle install。然后乘客抛出了这个例子。它没有让我任何意义。那可能是什么？我可以获得任何有关例外的详细描述吗？
Exeption on apache error_log:

您需要在apache配置文件中将RailsBaseURI指令更改为RackBaseURI。 RailsBaseURI用于Rails 1和Rails 2应用程序，而RackBaseURI是Rails 3的用法。
有人报告说，丢失的config.ru文件导致了相同的错误消息。
您可以查看http://groups.google.com/group/phusion-passenger/browse_thread/thread/e5c7495a6fef4ba7上的讨论。

请检查您正在使用的Gems版本。就我而言，Gemfile中存在一个问题。在我的情况下，我使用较低版本的宝石'rubyzip'，'0.9.9'，我更新到宝石'rubyzip'，'1.0.0'解决了这个问题。红宝石拉链
