compare-page.component.ts

import {AngularFireModule} from "@angular/fire";
import {AngularFireAnalyticsModule, AngularFireAnalytics} from "@angular/fire/analytics";

@NgModule({
   imports: [
   .....
       AngularFireModule.initializeApp(environment.firebase),
       AngularFireAnalyticsModule,
   ],
   providers: [
      AngularFireAnalytics,
      ...fromServices.services,
   ],

您是否知道缺少什么？

我使用了本教程：https://www.positronx.io/firebase-authentication-in-angular-8-with-angularfire2/

没有名为AngularFireAnalytics的提供程序。因此，您需要将providers数组更改为以下内容：

  providers: [
      ...fromServices.services,
   ],

然后使用Firebase分析在组件中执行以下操作：

import { AngularFireAnalytics } from '@angular/fire/analytics';

constructor(analytics: AngularFireAnalytics) {
  analytics.logEvent('custom_event', { ... });
}

在这里检查：
