How to fix: "@angular/fire"' has no exported member 'AngularFireModule'.ts(2305) ionic, firebase, angular

Issue

I'm trying to connect my app with a firebase db, but I receive 4 error messages on app.module.ts:

'"@angular/fire"' has no exported member 'AngularFireModule'.ts(2305),
'"@angular/fire/storage"' has no exported member 'AngularFireStorageModule'.ts(2305)
'"@angular/fire/database"' has no exported member 'AngularFireDatabaseModule'.ts(2305)
'"@angular/fire/auth"' has no exported member 'AngularFireAuthModule'.ts(2305)

here is my package.json file:

And here is my app.module.ts:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';
import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { ClientPageModule } from './client/client.module';
import { environment } from '../environments/environment';
import { AngularFireModule } from '@angular/fire';
import { AngularFireAuthModule } from '@angular/fire/auth';
import { AngularFireStorageModule } from '@angular/fire/storage';
import { AngularFireDatabaseModule } from '@angular/fire/database';

@NgModule({
  declarations: [AppComponent],
  entryComponents: [],
  imports: [
    BrowserModule,
    IonicModule.forRoot(),
    AppRoutingModule,
    ClientPageModule,
    AngularFireModule.initializeApp(environment.firebaseConfig),
    AngularFireAuthModule,
    AngularFireStorageModule,
    AngularFireDatabaseModule
  ],
  providers: [{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy }],
  bootstrap: [AppComponent],
})
export class AppModule {}

Here is my tsonfig.ts file

  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,

    "skipLibCheck": true 
  }
}

Solution

@angular/fire ^7.0.4 does not match this one dependency: firebase ^7.24.0.

Either you depend on firebase 9.0.2 - or downgrade to @angular/fire ^6.1.5.

Just see the documentation which I've linked, it clearly states that.

"@angular/fire": "~7.0.4",
"firebase": "~9.0.2",

---

Besides, @ionic had been superseded by @capacitor and devkit goes into devDependencies.
