node.js的 node-sass问题

报错如下
Error: Missing binding D:\0OldE\0web\javascript\xiaomi\node_modules_node-sass@4.14.1@node-sass\vendor\win32-x64-64\binding.node
Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 10.x

Found bindings for the following environments:

• Windows 64-bit with Node.js 14.x

尝试了很多个方法
首先有安装淘宝镜像的
1、先重装node-sass
cnpm insatall node-sass --save
这个方法还是报错
2、再查资料发现。下面那句 Windows 64-bit with Node.js 14.x说明版本不一样
查到一个答案如下https://blog.csdn.net/ruan0802/article/details/107566729/
然后cnpm rebuild node-sass
报错多了一个

处理了很久，最后这样解决了
1、把所有的node_modules文件夹删除
2、把项目里的package.json删除
3、把node.js重装
4、把gulp重新下载，就可以运行了
