Question

我被我的角火2离线/离子3应用程序困住了。当我尝试将我的应用程序上传到离子视图时，它一直给我这个错误。当我为Android构建时，当我使用离子实验室时，它没有错误。

我看到其他人有一个polyfill问题他们建议做：

npm install promise-polyfill --save-exact

但它对我不起作用，错误仍然存在。这些是我的版本（package.json）：

＆＃34; firebase＆＃34;：＆＃34; ^ 4.3.0＆＃34;，＆＃34; angularfire2＆＃34;：＆＃34; ^ 4.0.0-rc0＆＃34;，＆＃34; angularfire2-offline＆＃34;：＆＃34; ^ 4.2.4＆＃34;，

Answer 1

npm install angularfire2 firebase promise-polyfill --save

angularfire2已更新了他们的文档。

https://github.com/angular/angularfire2/blob/master/docs/Auth-with-Ionic3-Angular4.md

Answer 2

将angularfire2安装到我的应用程序后，我有完全相同的错误;只有在将代码推送到离子pro平台时。首先，我也为ios构建了错误，通过将angularfire2更新为另一个版本来逃脱：

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

也许你可以尝试一下？
