[ERROR] Network connectivity error occurred, are you offline?

        If you are behind a firewall and need to configure proxy settings, see:
        https://ionicframework.com/docs/cli/configuring.html#using-a-proxy

        Error: getaddrinfo ENOTFOUND d2ql0qc7j8u4b2.cloudfront.net d2ql0qc7j8u4b2.cloudfront.net:443
            at errnoException (dns.js:50:10)
            at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26)

错误分析：出现错误的原因是国内访问icon服务器的项目下载失败，无法连接。

解决方案：使用代理，推荐淘宝NPM镜像：
