Question

npm start会启动我的应用程序，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
┌──────────┬────┬──────┬──────┬────────┬─────────┬────────┬─────────────┬──────────┐
│ App name │ id │ mode │ pid  │ status │ restart │ uptime │ memory      │ watching │
├──────────┼────┼──────┼──────┼────────┼─────────┼────────┼─────────────┼──────────┤
│ app      │ 0  │ fork │ 4681 │ online │ 0       │ 0s     │ 11.508 MB   │ disabled │
└──────────┴────┴──────┴──────┴────────┴─────────┴────────┴─────────────┴──────────┘
 Use `pm2 show <id|name>` to get more details about an app

在我得到的日志中：

PM2: 2015-06-04 17:12:39: Script /home/user/app/app.js had too many unstable restarts (15). Stopped. "errored"

这是我的package.json：

  1 {
  2   "name": "app",
  3   "version": "0.0.0",
  4   "private": true,
  5   "scripts": {
  6     "start": "node ./bin/www"
  7   },
  8   "dependencies": {
  9     "body-parser": "~1.12.4",
 10     "cookie-parser": "~1.3.5",
 11     "debug": "~2.2.0",
 12     "express": "~4.12.4",
 13     "jade": "~1.9.2",
 14     "morgan": "~1.5.3",
 15     "serve-favicon": "~2.2.1",
 16     "stylus": "0.42.3"
 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？

Answer 1

~~首先，我尝试node ./bin/www并确保其正常运行。~~

我不确定＆＃34;官方＆＃34;解决这个问题的方法是，但这应该有效：
您可以将未捕获的异常处理程序放入代码中，只需写入文件或执行其他操作即可。

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

修改根据您的评论，您遇到问题的原因是app.js不是您应用中的真正切入点。真正的切入点是./bin/www

所以你需要告诉PM2启动那个文件，而不是像这样app.js：
pm2 start ./bin/www

pm2 start app.js在15次重启后退出
