需要手动将 node-sass@4.12.0 依赖文件下载下来，存放到NPM缓存路径当中，这样执行 npm i的时候就直接可以从缓存里面安装，解决请求镜像源下载异常问题

node-sass@4.12.0对应的依赖下载地址： win32-x64-72_binding.node

默认的NPM缓存路径：C:\Users\用户\AppData\Roaming\npm-cache\

将依赖文件放到 npm-cache\node-sass\4.12.0当中

通过CMD查询具体本机的NPM缓存路径：

# 查看当前 npm 缓存路径
npm config get cache

最后执行安装node-sass查看是否成功

npm i node-sass@4.12.0
