在Function.Module.\u解析文件名（Module.js:470:15）
在Function.Module.\u加载（Module.js:418:25）
at Module.require（Module.js:498:17）
根据需要（内部/module.js:20:19）
反对。（/Users/mps/Sites/my-app/server.js:10:20）
在模块处编译（模块js:571:32）
在Object.Module.\u extensions..js（Module.js:580:10）
在Module.load（Module.js:488:32）
在tryModuleLoad时（module.js:447:12）
在Function.Module.\u加载（Module.js:439:3）
这破坏了我日志的格式/结构，因为它是纯文本，而不是我从winston
收到的格式化JSON
我确信这是PM2问题/配置错误，因为如果我运行node server.js
控制台输出就是JSON对象
我是否必须在PM2ecosystem.json
文件中设置特定属性
我如何告诉PM2忽略节点的uncaughtException
我想到的唯一替代方法（我还没有尝试过）是将我的winston transport更改为winston.transports.File
，将所有日志重定向到stdout
，并告诉PM2将stderr
保存到另一个文件中，但我不同意
