当我尝试运行 npm run dev 时，输出：
username:backend-atop-oa fulwin$ npm run dev

npm ERR! /Users/fulwin/.npm/_logs/2018-01-08T07_29_15_303Z-debug.log之前运行都好好的今天突然就不能用了，我百度了好多解决办法，有的说是端口占用，可是我看了端口并没有占用，默认是8080，我在启动时执行：
npm run dev --port 8088似乎没有作用，依然报错，然后我又尝试修改config/index.js配置文件，将其中的默认端口改为8088，无果。
然后我又尝试：
rm -rf node_modules/
rm package-lock.json
npm cache clean --force
npm install依然出现上述错误。
接下来我企图从上面的log日志文件里找到答案 /Users/fulwin/.npm/_logs/2018-01-08T07_29_15_303Z-debug.log 在日志中，输出以下信息，似乎对于我并没有帮助，依然不知问题出在哪：

望各位大佬帮我指点指点
看报错信息
说的是没有指定
localhost在
c:\windows\system32\drivers\etc\hosts文件中添加127.0.0.1 localhost
