从gitee上拉下来一个vue项目，上面没有提交项目里的node_modules文件夹，所以需要自己执行npm i 安装，但是安装完成之后运行项目后却报错了：
//中间部分都是同下面的一种错误
error in ./src/assets/css/home/dataProfile.scss

出现这种错误我当时就想的是可能没有把需要的插件或者包都安装下来，所以就重新执行了一次npm i 还是这种报错，我就百度一了一会找到一个博主说需要安装ajv(根本没有听说过这种东西，这是啥玩意)
然后就安装了这个插件： npm install ajv@^6.0.0
为了保险我又重新 npm i 安装了一下(可用可不用)
才运行npm run dev
