解决：

1.下载 node-sass 依赖

npm install node-sass --save-dev

还是报错

2.输入命令

npm install -g cnpm --registry=https://registry.npm.taobao.org

报错如下：

cnpm - 解决 " cnpm : 无法加载文件 C:\Users\93457\AppData\Roaming\npm\cnpm.ps1，因为在此系统上禁止运行脚本。有关详细信息 。。。

在win10 系统中搜索框输入 Windos PowerShell

选择 管理员身份运行

打开了powershell命令行之后,输入

set-ExecutionPolicy RemoteSigned

更改权限为A

输入get-ExecutionPolicy

如下：

3.输入命令

cnpm install node-sass --save

4.运行

npm run dev

亲测成功！
