Error: getaddrinfo ENOTFOUND localhost

一、背景：

在启动vue ui���时候，报错了。

报错信息：

node:events:491

      throw er; // Unhandled 'error' event

      ^

Error: getaddrinfo ENOTFOUND localhost

    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:107:26)

Emitted 'error' event on WebSocketServer instance at:

    at Server.emit (node:events:513:28)

    at GetAddrInfoReqWrap.doListen [as callback] (node:net:1934:12)

    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:107:17) {

  errno: -3008,

  code: 'ENOTFOUND',

  syscall: 'getaddrinfo',

  hostname: 'localhost'

}

Node.js v18.14.2

二、解决办法

修改host，在hosts文件中，加入

127.0.0.1 localhost
