node.js – pm2 start app.js在15次重启后退出

npm start会启动我的应用程序就好了但是当我这样做时：

pm2 start app.js

我明白了：

[PM2] Spawning PM2 daemon
[PM2] PM2 Successfully daemonized
[PM2] Process app.js launched

 Use `pm2 show <id|name>` to get more details about an app

在我得到的日志中：

这是我的package.json：

  2   "name": "app",3   "version": "0.0.0",4   "private": true,5   "scripts": {
  6     "start": "node ./bin/www"

 17   }
 18 }

节点版本：v0.10.38
pm2版本：0.12.15

我怎么调试这个？我不确定为什么会失败,是否还有其他地方需要检查？我的app.js文件？

解决方法

首先,我尝试使用node ./bin/www并确保其正常工作.

我不确定解决这个问题的“官方”方式是什么,但这应该有效：
您可以将未捕获的异常处理程序放入您的代码中,该代码只是写入文件或执行其他操作.

process.on('uncaughtException',function(err) {
    console.log('Caught exception: ' + err);
    throw err;
});

编辑：
根据您的评论,您遇到问题的原因是因为app.js不是您应用程序中的真正入口点.真正的切入点是./bin/www

所以你需要告诉PM2启动该文件而不是像这样的app.js：pm2开始./bin/www
