Module not found: Error: Can‘t resolve ‘path‘ in XXX webpack ＜ 5

webpack5

webpack compiled with 2 errors报错：

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: { "path": require.resolve("path-browserify") }'
        - install 'path-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "path": false }

解决方案：
1.安装 npm install node-polyfill-webpack-plugin
2.在vue.config.js中配置

const { defineConfig } = require('@vue/cli-service')
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin')

module.exports = defineConfig({
  transpileDependencies: true,
  lintOnSave: false,
  configureWebpack: {
    plugins: [new NodePolyfillPlugin()]
  }
})
