Question

我很擅长在简单的rails应用程序上使用Thin服务器。它运行得很好，除了，当我去应用程序中的任何页面时，我在浏览器上得到的这个中有1个或更少：

Status: 500 Internal Server Error Content-Type: text/html
Application error

Change this error message for exceptions thrown outside of an action (like in Dispatcher         setups or broken Ruby code) in public/500.html

并在日志中：

有没有人见过这个？

对我来说最棒的是rails-1.2.3在你的堆栈中。我相信如果您bundle exec thin您将获得正确版本的rails，但您也可以通过删除所有不依赖于您应用的宝石来强制执行此操作。

虽然rvm非常适合开发，但我不相信它在系统级别安装时会带来很多价值，而且我听说很多人在生产系统（特别是CentOS）上挣扎于获取环境正确运行的用户瘦身。如果您不熟悉rails部署，请考虑使用乘客之类的东西，并且只考虑sudo gem install依赖项。

将Thin Server与简单的Rails应用程序一起使用时，日志中出现意外错误
