webpack webpack < 5 used to inc

webpack5中移除了nodejs核心模块的polyfill自动引入，所以需要手动引入。

2 vue.config.js中修改配置

// 头部引入
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin')

configureWebpack: (config) => {
    const plugins = []
    plugins.push(new NodePolyfillPlugin())
}
// 或者
configureWebpack: {
    plugins: [new NodePolyfillPlugin()],
}
