显示找不到node_modules/node-sass/vendor模块。去文件夹一看，还真的是没有，应该是在安装全局依赖的时候，没有安装到vendor，通过rebuild命令重新安装一下就可以啦。
解决办法，运行：npm rebuild node-sass
huyikangdeMacBook-Pro:vbap-widgets kangkang$ npm rebuild node-sass
> node-sass@4.6.1 install /Users/kangkang/vbap-widgets/node_modules/node-sass

Binary is fine

成功，去文件夹下查看，确实有了vedor文件夹，再 npm run dev启动工程就可以啦。
