 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[email protected]和[email protected]版本

6、至此所有问题解决，重新运行项目
