错误的原因：
1、npm install 下载node-sass和sass-loader的版本不一致导致的
2、首先检查本地node.js的版本
node -v
3、根据node.js的版本，找到对应的node-sass和sass-loader的版本
4、先卸载原来安装的node-sass和sass-loader
npm uninstall node-sass sass-loader
5、 然后安装node.js对应的版本
npm install sass-loader@版本号 node-sass@版本号 --save-dev
因为我的node.js版本为：16.13.1，所以我对应的sass-loader@10.2.0和node-sass@6.0.1版本
6、至此所有问题解决，重新运行项目
