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 ┌──────────┬────┬──────┬──────┬────────┬─────────┬────────┬─────────────┬──────────┐ │ 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：

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？
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
