输入npm install 

报以下错误

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! node-sass@4.13.1 postinstall: `node scripts/build.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the node-sass@4.13.1 postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

　　

这个是因为sass安装时获取源的问题，修改sass安装的源，使用taobao的npm

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

然后运行

npm install
