BREAKING CHANGE: webpack ＜ 5 used to include polyfills for node.js core modules by default.

执行启动项目命令时，出现 BREAKING CHANGE: webpack ＜ 5 used to include polyfills for node.js core modules by default。。。

报错，原因是由于在webpack5中移除了nodejs核心模块的polyfill自动引入，所以需要手动引入

解决方案：

1 . 安装 npm install node-polyfill-webpack-plugin

---

2 . 然后在vue.config.json中添加：

const NodePolyfillPlugin = require('node-polyfill-webpack-plugin')

configureWebpack: {
	plugins: [new NodePolyfillPlugin()]
}
