报错情况

error when starting dev server:Error: listen EACCES: permission denied 127.0.0.1:80    at Server.setupListenHandle [as _listen2] (node:net:1415:21)    at listenInCluster (node:net:1480:12)    at GetAddrInfoReqWrap.doListen [as callback] (node:net:1629:7)    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:111:8)

启动项目加个端口（任意）

npm run dev -- --port 81

报错原因

文件package.json 端口80冲突

  "scripts": {    "dev": "vite --port 80--open",   //端口80冲突    "build": "vue-tsc && vite build",    "preview": "vite preview"  },
