Ruby on rails 项目:我升级了服务器(应用程序、配置)上的文件，并成功运行了 bundle install。然后乘客抛出了异常(exception)。它没有让我有任何感觉。那可能是什么？我可以在任何地方获得豁免的详细说明吗？

谢谢!
最佳答案
您需要在 apache 配置文件中将 RailsBaseURI 指令更改为 RackBaseURI。 RailsBaseURI 适用于 Rails 1 和 Rails 2 应用程序，而 RackBaseURI 则适用于 Rails 3。
有人报告说，缺少 config.ru 文件会导致相同的错误消息。
您可能想查看 http://groups.google.com/group/phusion-passenger/browse_thread/thread/e5c7495a6fef4ba7 上的讨论。
