This dependency was not found:  * components/Header in ./node_modules/babel-loader/lib!./node_modules/vue-loader/lib/selector.js?type=script&index=0!./src/pages/Index.vue

经查发现Index.vue路径引入错误，import PageHead from 'components/Header';改import PageHead from '../components/Header';大功告成！

error in ./src/components/Header/index.vue

Module build failed: Error: Cannot find module 'node-sass'

报错没有找到模块，在本地安装node-sass即可！
