Error: getaddrinfo ENOTFOUND localhost

一、背景：

在启动vue ui的时候，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
