没有任何幽灵进程在运行..。这是很好的工作，直到我做了一个新的npm安装整个项目。有什么想法？

Answer 1

根据日志，您使用的是群集。您可能试图在同一个端口上侦听每个子进程，这将在启动第二个子进程后抛出错误。

Answer 2

我可以从你的日志中看到：

您的主服务器启动于127.0.0.1:5858。

然后SocketCluster尝试从127.0.0.1:5858开始

因此，如果一个服务器已经是5858端口，那么其他服务器如何使用5858？

所以请换个端口来解决这个问题。

Answer 3

当两个以上的应用程序使用一个portno时，就会出现此错误。

Use this command 
1) `netstat -tulpn` (Commans for show all the process on server) 
2)  then kill the process with the process number. like kill 2043
