npm安装node-sass总是报错，错误信息如下：

错误原因：
node-sass会依赖一个二进制文件binding.node，当下载node-sass时，会先下载这个文件，如果本地没有安装过这个文件，会在github下载该文件并将其缓存到全局;一般下载的时候会因为网络的原因下载失败，node-sass会尝试在本地编译binding.node，这个过程就需要用python。这时就会报错说没安装python，如果binding.node下载成功的话就不会报这个错

解决办法：将npm源设置成淘宝镜像源，将binding.node源也改为淘宝镜像源

npm config set registry https://registry.npm.taobao.org
npm config set SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass/

如果本地已经有了node-sass，要先把之前的卸载

npm uninstall node-sass

安装node-sass即可安装成功

后续可能还会报错

Error: Node Sass version 7.0.1 is incompatible with ^4.0.0.
node sass报错
项目由于安装的node版本不同，安装依赖后导致项目运行失败并有报错问题。

解决方案：
如果是先执行了npm install之后发现项目运行时报Node Sass version 7.0.0 is incompatible with ^4.0.0类似这样的错，那么需要先卸载已下载好的node-sass依赖

1、npm uninstall node-sass;
2、npm i -D sass;
3、npm run dev；

用npm 卸载安装不了的同学可以试一下cnpm
npm install -g cnpm -registry=https://registry.npm.taobao.org

这样就成功了~~~~~
