Error: getaddrinfo ENOTFOUND dev.maxim.top at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:67:26)
解决办法：Error: getaddrinfo ENOTFOUND dev.maxim.top at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:67:26)
错误提示，应该是无法去访问dev.maxim.top，然后去全局搜索dev.maxim.top，发现在webpack.dev.config.js文件中有，由于这
个dev.maxim.top无法访问而导致的，我们只需将dev.maxim.top改成localhost，重新 npm run dev 就可以成功启动了。
npm 报错This is probably not a problem with npm. There is likely additional logging output above.
可能是版本的问题
重新 npm install
然后 npm i -D webpack-dev-server@3.0.0
再 npm run dev
重新安装一次，如果还是不可以的话，在把之前装的都清空
rm -rf node_modules
rm package-lock.json
npm cache clear --force
npm install
然后对项目进行npm install，在项目中会生成一个文件夹如下：
此时再执行npm start 项目就启动起来
