关于前端:记录用脚手架创建-Vue3-遇到的插件坑

我的项目架构
Vue3 + element-plus + echarts + axios + 高德地图 + sass

插件包
amfe-flexible + postcss-pxtorem、vuex-persistedstate、sass-loader

创立前提
1、把脚手架降级到最新
2、把 npm 降级到最新
留神：用管理员权限操作

报错/正告

error: 'XXX' is defined but never used (no-unused-vars）//解决办法：package.json 中增加"rules": {   "generator-star-spacing": "off",   "no-tabs":"off",   "no-unused-vars":"off",   "no-console":"off",   "no-irregular-whitespace":"off",   "no-debugger": "off"}

 Error: PostCSS plugin postcss-pxtorem requires PostCSS 8.” //解决办法，降级为："postcss-pxtorem": "^5.1.1",

 Error: Cannot find module 'vue-loader-v16/package.json' //把 cnpm 装置换成 npm 装置

"export 'default' (imported as 'echarts') was not found in 'echarts'//改成  import * as echarts from "echarts";

  sass-loader   //版本改成 "sass-loader": "^7.1.1"
