Answer 1

换npm源吧

Answer 2

换个node-sass版本，这个版本没有预编译的二进制文件
要么就别用cnpm装

Answer 3

网上给的各种答案 npm/node版本 以及npm/cnpm/yarn等 依然成功不了。简单粗暴的方式就是拿同事的包丢进去or自己网上下载一个相应版本的包丢进去，然后再npm install一遍。 -- 即安装失败之后自己下载一个方法哦node_modules中

Answer 4

看一下自己npm的源和package-lock里的源是不是同一个 不是的切一下就好了

Answer 5

卸载python3，重新安装python2，环境变量替换成2的安装路径
