cordova plugin add出現CERT_UNTRUSTED錯誤解決方法

目前使用ionic+cordova完成hybmid app開發，在安裝geolocation插件時爆出來一個莫名的錯誤：

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)

原因是因為我自己重新設置了npm倉庫為淘寶的npm鏡像倉庫，由于某些安全原因無法獲取cordova的相關插件，解決辦法很簡單：

npm config set strict-ssl false

以上。
