錯誤：polifill promise angularfire2

Question

我卡在我的角射擊-2離線/ ionic3應用程序。當我嘗試將我的應用上傳到離子視圖時，它一直給我這個錯誤。當我爲Android構建或使用離子實驗室時，它沒有任何錯誤。

我看到其他人有填充工具的問題，他們建議做：

npm install promise-polyfill --save-exact 

，但它不爲我工作，錯誤仍然存​​在。這些都是我的版本（的package.json）：

「火力點」： 「^ 4.3.0」， 「angularfire2」： 「^ 4.0.0-RC0」， 「angularfire2脫機」：「^ 4.2。 4「，

Answer 1

安裝angularfire2到我的應用程序後，我有完全相同的錯誤;只有在將代碼推送到離子平臺的時候。 首先我對IOS的錯誤建設，以及，通過更新angularfire2到另一個版本逃走了：

npm i --save angularfire2@4.0.0-rc.1 

也許你可以試試嗎？

NPM安裝angularfire2火力承諾，填充工具--save

angularfire2已經更新了他們的文檔。
