出错原因就是sass不支持当前的环境，那么在当前环境重新安装一下就好了

1、查看本地nodejs的版本号和node-sass的版本号

node -v        ---查看nodejs的版本号以及查看其是否安装

node-sass -v   ---查看node-sass的版本号以及查看其是否安装

2.、卸载node-sass，但是如果卸载不成功，直接找到node-sass文件夹，删除

npm uninstall --save node-sass   --记住执行这个命令前，需要先进入到对应的文件目录才可以删除

如图（如下图即可）：

3、重新安装更新版本的node-sass即可

npm install --save node-sass    (cnpm install --save node-sass   )
（这个也要在指定文件夹执行，并进行本地安装）

 

这样就可以了！！！！！！！！！

如下图所示：
