解决方案

请确保你有Python2的环境后，那么都是由于node.js的版本与node-sass和sass-loader版本互相不兼容导致！

Python2下载连接：https://www.python.org/ftp/python/2.7.18/python-2.7.18.amd64.msi，安装完成打开cmd命令行输入python查看是否有Python2的环境

官网解释：node-sass - npm

1.如果你是Node16版本的话，可以参考以下修改方案，打开项目的package.json文件，找到node-sass和sass-loader

1.  
   "node-sass": "^6.0.1",
2.  
   "sass-loader": "^10.0.1",

2.如果你是Node14版本的话，可以参考以下修改方案，打开项目的package.json文件，找到node-sass和sass-loader

1.  
   "node-sass": "^4.13.1",
2.  
   "sass-loader": "^8.0.2",

以Node16为例：

 3.都修改好以后，重新npm install即可！如果对您有帮助的话麻烦给博客点个赞！谢谢！
