angular - 带有Angular-map（agm）的İonic 3未捕获（承诺）：TypeError：Object（...）不是函数

Question

我有使用 Angular 谷歌地图的 ionic 3 项目，经过一些更新后，地图页面出现问题，它说

未捕获（承诺）：TypeError: Object(...) is not a function TypeError: Object(...) is not a function at new FitBoundsService

如何解决这个问题？

纽约环境。

离子：

ionic (Ionic CLI)  : 4.9.0 (/usr/local/lib/node_modules/ionic)
Ionic Framework    : ionic-angular 3.9.5
@ionic/app-scripts : 3.2.1

科尔多瓦：

cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
Cordova Platforms     : android 7.1.4, ios 4.5.5
Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 2.4.1, (and 13 other plugins)

系统：

ios-deploy : 1.9.2
NodeJS     : v8.12.0 (/usr/local/bin/node)
npm        : 6.9.0
OS         : macOS Mojave
Xcode      : Xcode 10.2.1 Build version 10E1001

1. 我已将 agm/core 降级为 1.0.0-beta2 和 3
2. 我已经安装了 rxjs 6 ，但它给了我更多的错误，因为我使用的是 angular 5。

这是 mu package.json
