npm: no such file or directory, scandir '.../node_modules/node-sass/vendor'(转)

在启动vue工程项目时报错：

npm install
npm run dev

错误日志：

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

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。
