vue项目npm run serve 报错，Error: read ECONNRESET at TCP.onStreamRead

背景：vue2的项目，之前npm run serve一直可以正常使用，突然每次启动都会报错了，报错信息如下：

node:events:492

throw er; // Unhandled 'error' event

^

Error: read ECONNRESET

at TCP.onStreamRead (node:internal/stream_base_commons:217:20)

Emitted 'error' event on Socket instance at:

at emitErrorNT (node:internal/streams/destroy:151:8)

at emitErrorCloseNT (node:internal/streams/destroy:116:3)

at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {

errno: -4077,

code: 'ECONNRESET',

syscall: 'read'

}

做了很多尝试，和node版本无关，和npm缓存也无关，和node_modules的依赖包也无关。

原因应该是：webSocket 走了本地代理，报错直接崩。关了本地websocket代理就行了

vue.config.js中的proxy中加上ws: false 重新npm run serve启动项目就行了。
