很多人会以为是  python 找不到，而去安装python 然后各种 管理员权限打开执行：npm install --global --production windows-build-tools。
最后还是不行，仔细看会发现标红得错误信息，应该是 node-sass安装不成功添加一个<code>node-sass</code> 的数据源，在install 就OK了
<h3>解决方法：</h3>
<h3>　　npm config set sass_binary_site=https://npm.taobao.org/mirrors/node-sass</h3>
再执行 npm install 就可以了
