vue+webpack5：If you want to include a polyfill you need to

升级@vue/cli 5.0.1，发现 const path = require("path")异常

发现默认webpack 是，提示v5区别于v4不再自动引入Polyfills，需要手动添加

按照控制台提示

1、安装path-browserify

npm install path-browserify

2、在vue.config.js文件中配置

configureWebpack() {return {resolve: {alias: {"@": resolve("src"),},fallback: {path: require.resolve("path-browserify"),},},}},
