npm run dev 报错的问题 启动失败后出现问题，BrowserslistError相关的文件报错问题

当我的vue环境什么的都搭好的时候，最后一步npm run dev 问题就来了，我修改一下index.js。端口8080修改成其他8099 还是报错，后面也是查一下资料搞好久才解决掉的，后面我把Browserlist相关的文件删除了，重新启动一下npm run dev才成功的，希望给学习vue的同学在适配环境能够更好解决掉。

应该是browsercraigslist的相关文件跟package,json不能同时存在的意识罢.,望大神经过帮忙修正,..

所以然后尝试把browsercraigslist相关文件删了，运行npm run dev

很高兴也把问题解决，希望给更多的人把问题给解决掉
