cordova plugin add出现CERT_UNTRUSTED错误解决方法

介绍

   目前使用ionic+cordova完成hybmid app开发，在安装geolocation插件时爆出来一个莫名的错误：

Fetching from npm failed: CERT_UNTRUSTED Error: CERT_UNTRUSTED     at SecurePair.<anonymous> (tls.js:1367:32)     at SecurePair.emit (events.js:92:17)     at SecurePair.maybeInitFinished (tls.js:979:10)     at CleartextStream.read [as _read] (tls.js:471:13)     at CleartextStream.Readable.read (_stream_readable.js:340:10)     at EncryptedStream.write [as _write] (tls.js:368:25)     at doWrite (_stream_writable.js:225:10)     at writeOrBuffer (_stream_writable.js:215:5)     at EncryptedStream.Writable.write (_stream_writable.js:182:11)     at write (_stream_readable.js:601:24)

         原因是因为我自己重新设置了npm仓库为淘宝的npm镜像仓库，由于某些安全原因无法获取cordova的相关插件，解决办法很简单：

npm config set strict-ssl false

以上。
