egg项目npm start启动报错

Question

当使用npm start命令时报如下错误：

[egg-scripts] Save log file to /root/logs

本以为是端口被占用问题

但是使用npm stop停止时提示：

[egg-scripts] stopping egg application with --title=egg-server-nodejs-lo
[egg-scripts] can't detect any running egg process
[egg-scripts] stopped

通过ps查看node进程
[root@VM_129_145_centos nodejs-lo]# ps -ef|grep node
root 6874 4763 0 2020 pts/0 00:00:00 grep --color=auto node

不太明白上面啥意思，但是使用kill命令也没有用

莫名的问题出现，只是因为在项目里加了定时任务，其他代码没做什么改变

想请教下大家这个问题该如何解决？

非常感激！

你把文件全部删掉，然后再重新上传文件，如果npm start又出现报错，可以先试试 npm stop，可能是端口占用，我就是这么解决的
