原因：@vue/cli 依赖 webpack@4，它自带的 webpack 配置无法兼容 webpack@5 ，于是就报错，不能继续编译。如果在使用 @vue/cli，那么请不要贸然升级 webpack@5。

解决办法：

删除node_modules 和 package-lock.json
手动在 package.json 的 devDependencies 里添加 "webpack": "^4.47.0",（只要是4就好
重新安装全部依赖：npm install

一般情况可以解决，但如果出现以下这个错误：

根据提示可以强制安装：npm install --force 或 npm install --legacy-peer-deps
