ruby-on-rails - 乘客错误 : The application spawner server exited unexpectedly: Unexpected end-of-file detected

Question

这只是前几天工作，但我刚刚将我的代码更新到运行乘客 2.2.4 的审查服务器，而我的 2.3.4 rails 应用程序现在无法在那个盒子上启动。

乘客报告:

Passenger encountered the following error:

The application spawner server exited unexpectedly: Unexpected end-of-file detected.

Exception class:

有任何想法吗？

弄清楚了。我终于检查了主要的 apache 错误日志，发现有一个
我的一颗 gem (facebooker 配置)有问题。

要解决 facebooker 问题，请确保在 config/facebooker.yml 中有一个适合您的环境的条目

我认为乘客至少应该提供一个选项来查看更多在 apache 的错误日志中报告的堆栈跟踪。会更有帮助。
