2.结论

node-sass的问题

npm ERR! [email protected] postinstall: `node scripts/build.js`

3.解决

//windows设置变量 sass_binary_site，指向淘宝镜像地址。
set SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass/ && npm install node-sass

或者

//设置全局镜像源：
npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/
