先看下我的報錯
username:backend-atop-oa fulwin$ npm run dev
> [email protected] dev /Users/fulwin/Documents/codes/backend-atop-oa

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我是先刪除了node_modules，重新npm install 沒用（重新安裝依賴）
rm -rf node_modules/
rm package-lock.json
npm cache clean --force
npm install
最後發現報錯是這個意思：意思是 沒有找到指定localhost
Error: getaddrinfo ENOTFOUND localhost
at errnoException (dns.js:50:10)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26
解決方法：config=>index.js中把host改爲127.0.0.1
然後再次試試 npm run dev
