Estou aprendendo Angular procurando ajuda para consertar o erro: Estou seguindo este link: https://github.com/angular/angularfire2/blob/master/docs/install-and-setup.md para criar um pequeno angular aplicativo com angular2 e angularfirestore2
mas quando clico em servir, recebo o erro abaixo no console do navegador.
StaticInjectorError[AngularFirestore]:

Tentei pesquisar no Google, mas não encontrei a solução exata, nada funcionou para mim :(,
Aqui está o que eu segui: 1) Nó instalado versão 8.9.1 2) npm install -g @ angular / cli -> Versão 1.5.2 3) ng new 'project-name' 4) npm install angularfire2 firebase --save
Aqui está meu arquivo app.module.ts:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { AngularFireModule } from 'angularfire2';
import { environment } from '../environments/environment';
@NgModule({
imports: [
BrowserModule,
AngularFireModule.initializeApp(environment.firebase)
],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule {}
app.component.ts:
import { Component } from '@angular/core';
import { AngularFirestore } from 'angularfire2/firestore';
import { Observable } from 'rxjs/Observable';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'app';
constructor(db: AngularFirestore) {}
}
environmentemnt.ts:
export const environment = {
production: false,
firebase: {
apiKey: 'xxxxx',
authDomain: 'aaaaaaa',
databaseURL: 'bbbbbbbbbbbbbbbbbb',
projectId: 'aaaaaaaaaaaaaa',
storageBucket: 'aaaaaaaaaaaa',
messagingSenderId: 'aaaaaaaaaaaaa'
}
};
então ng serve, e estou recebendo o erro acima ...
