javascript - IONIC 4：插件 firebase 和 google-maps 的问题 - 默认 FirebaseApp 未在此进程 com.superagent.agent 中初始化。一定要打电话

Question

我正在使用 Ionic 4 开发 android 应用程序，现在在使用 @ionic-native/google-maps 和 @ionic-native/firebase-messaging 时遇到问题。我无法接收推送通知并触发 Firebase 分析。但我的谷歌地图正常工作。另外，我正在为这些应用程序使用 Jscrambler

我总是在调用 fcm.getToken() 方法时遇到这个错误，即 fcm 是 firebase-messaging 插件的别名。这是错误：

ERROR Error: Uncaught (in promise): Default FirebaseApp is not initialized in this process com.xxx.xxx. Make sure to call FirebaseApp.initializeApp(Context) first.

和在 app.component.ts 上调用 firebase getToken 的函数在这里：

async initializeApp() {
  await this.platform.ready().then(() => {
    this.params.getUserData().then(userdata => {
      this.userData = userdata;
      // set fcm token when there is saved session on storage for all environment
      this.fcm.getToken().then(this.setDeviceId);
      this.fcm.onTokenRefresh().subscribe(this.setDeviceId);
      if(environment.production) {
        // init fbase analytics only on production & there is saved session on storage
        this.initFbAnalytics();
      }else{
        // subscribe to topic guest_dev when in develeopment mode
        this.fcm.subscribe("guest_dev");
      }
    });
  });
};

还有我的 package.json 文件依赖项：
