我们后台要了前端源代码，启动Vue项目后出现了这几行出错信息

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! node-sass@4.14.1 postinstall: `node scripts/build.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the node-sass@4.14.1 postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

于是，我就找了度娘，解决方案是在当前目录下对node-sass进行数据源设置

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

　　执行这个命令之前，千万别删安装的依赖包「node_modules」那个文件，直接执行上面那行代码就可；

     我们可爱的后台先把安装的node_modules删除了，然后执行的那行代码......后台谨记！！前端绝对不会出这个问题的，哈哈哈哈哈
