谢谢各位回复。
解决方法：
package.json 剔除了 node-sass ，独立安装 node-sass 就行了：npm install node-sass

[Altschmerz]

看这报错，是 python 执行路径没有找到，看看环境变量配置好了吗，或者安装 Windows-Build-Tools ，虽然 windows 自带 Windows-Build-Tools 。

[ambiouss]

update node-sass

[liliclinton]

不用这么麻烦，npm 版本大于 7 的话安装的时候带上 --legacy-peer-deps ，这样就不会安装 node-sass 了，如果一定需要就得配置下 node-gyp 的编译环境现场编译，这里报错是提示缺了 python2

[codingBug]

怎么感觉是需要翻墙的问题呢

[yin1999]

我感觉和楼上说的一致，试试设置环境变量 HTTP_PROXY 和 HTTPS_PROXY ，再 install

[fzcf]

node 和 npm 版本过高，换成 npm7.10.0 node v14.16.1

[idragonet]

@codingBug 已经配置代理了。

[idragonet]

@yin1999 已经配置梯子了。

[BenchWidth]

查看一下系统变量中有没有 %SystemRoot%\system32 这条变量，如果没有的话加上试试。

[wequart]

https://www.npmjs.com/package/node-sass
1. node-sass 有标注对应 node 版本应该下载的 node-sass 版本
2. 最好安装一个 windows-build-tools
3. 可以单独安装 node-sass 试试

[AV1]

不用点进来就猜到 node-sass 这坑爹的玩意

[YoRolling]

1. node-sass 可以试试使用 taobao 的镜像服务
2. 可以试试单独装一个 Python 试试，前两天也帮人看了这个问题，没装 wbt ，直接装了个 Python 就可以了
3. node-sass 已经不推荐了，可以的话，请选择使用 dart-sass

[rongchuan]

这种情况只能试了。
1.试试 cnpm ，要用新的淘宝源
2.使用 nrm,切换不同的源试试
3.看看之前开发这项目的人用的 Node 版本是多少，用 nvm 切到一致的版本，在 npm i
4.装个 python 试试好使不，我印象中我之前有类似 bug ，装个 python 就好了

[duan602728596]

Sass 现在是这个： https://www.npmjs.com/package/sass

[tmacLiu9527]

1. 删除 node_modules
2. 管理员身份运行 npm install --global windows-build-tools
3. npm install

如果上述不行, 将 node-sass 升级到 5.0 或以上
