进行npm install时报错 node-sass@4.14.1 postinstall: `node scripts/build.js` Failed at the node-sass@4.14.

项目进行 npm install时报错：

原因：找不到 node-sass@4.14.1

Failed at the node-sass@4.14.1 postinstall script.

解决方法：设置node-sass 的数据源

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

再次执行：npm install

程序不再报错!!!
