BREAKING CHANGE: webpack ＜ 5 used to include polyfills for nod

错误如下所示：

 ERROR  Failed to compile with 1 error                                                                                                                                                                     下午11:40:17error  in ./src/components/ProductParam.vue?vue&type=script&lang=js&Module not found: Error: Can't resolve 'process' in 'E:\mooc\vueMallsystem\mimall\src\components'BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.If you want to include a polyfill, you need to:- add a fallback 'resolve.fallback: { "process": require.resolve("process/browser") }'- install 'process'
If you don't want to include a polyfill, you can use an empty module like this:resolve.fallback: { "process": false }

检查下来是因为 webpack 5 以前的版本包含 polyfills。错误信息也给出了这个原因。
解决办法：

安装依赖

npm install path-browserify

vue.config.js中配置

const NodePolyfillPlugin = require("node-polyfill-webpack-plugin")configureWebpack:  {resolve: {fallback: {fs: false,crypto: require.resolve("crypto-browserify")}},plugins: [new NodePolyfillPlugin()],},
