以前也经常遇到这个错误，跟node-sass相关的，这边记录一下吧 大体意思就是用到了python，然后电脑要装一下 下面是报错内容，可以看一下你的是不是也雷同

这里有两个解决方案，方案二极其复杂，希望你用不上
方案一
如果用npm超时，可以尝试使用yarn
安装好 yarn 后 使用yarn安装依赖
yarn add node-sass方案二
使用以下命令安装所需工具，最好有梯子，如果没有梯子，可以去配置一下淘宝镜像（这里不赘述了，度娘）
npm install --global --production windows-build-tools可以看到，我在执行命令的时候，确实在占浏览的梯子
中途360等软件可能会报提醒，点击允许通过即可
异常情况
实在安装不了的情况也是有的 但是用powershell中断执行过程就会发现，其实主要是卡在VS和Python的脚本上，他其实是想依次安装这两个工具 作者这里也有解释：
https://www.npmjs.com/package/windows-build-tools
进入目录，手动安装（它不行我们就自己来装）
我这里装好Python后继续安装下一个 vs_BuildTools.exe
vs_BuildTools.exe点击修改，将Nodejs勾选上安装
在下拉框选择修复
做完后再尝试 npm install
