Error: listen EADDRINUSE :::4000解决办法

最近接手了一个angular1.6的老项目，在开发过程中遇到很多问题，代码层面及管理层面都有问题；

先记录一下代码运行时遇到的问题

[15:45:15] Starting 'startserver'...

启动webserver......

events.js:165

throw er; // Unhandled 'error' event

^

[15:45:16] 'startserver' errored after 1.4 s

[15:45:16] Error in plugin "gulp-shell"

Message:

Command node --nolazy app.js failed with exit code 1

查找原因：

Node.js端口冲突：listen EADDRINUSE :::4000

解决方案有两种：

1.修改端口号

2.杀掉占用4000端口的进程

查找占用端口的进程：

netstat -ano |findstr 4000

下一篇讲解一下如何通过端口杀掉占用进程
