npm run dev 時(shí)報(bào)錯(cuò)??！

當(dāng)我嘗試運(yùn)行 npm run dev 時(shí)，輸出：

username:backend-atop-oa fulwin$ npm run dev

> backend-atop-oa@1.0.0 dev /Users/fulwin/Documents/codes/backend-atop-oa
> webpack-dev-server --inline --progress --config build/webpack.dev.conf.js

      ^

之前運(yùn)行都好好的今天突然就不能用了，我百度了好多解決辦法，有的說是端口占用，可是我看了端口并沒有占用，默認(rèn)是8080，我在啟動(dòng)時(shí)執(zhí)行：

npm run dev --port 8088

似乎沒有作用，依然報(bào)錯(cuò)，然后我又嘗試修改config/index.js配置文件，將其中的默認(rèn)端口改為8088，無果。

然后我又嘗試：

rm -rf node_modules/
rm package-lock.json
npm cache clean --force
npm install

依然出現(xiàn)上述錯(cuò)誤。

接下來我企圖從上面的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，輸出以下信息，似乎對于我并沒有幫助，依然不知問題出在哪：
