Angularfire 2 Error: The specified authentication provider is not enabled for this Firebase

问题

I am creating a simple sample auth app with Ionic 2 and angularfire 2 as backend, when i try to create new user it says:

EXCEPTION: Error: Uncaught (in promise): Error: The specified authentication provider is not enabled for this Firebase.

But i already enabled firebase authentication in firebase console:

app.ts

import {App, Platform} from 'ionic-angular';
import {StatusBar} from 'ionic-native';
import {HomePage} from './pages/home/home';
import { FIREBASE_PROVIDERS, defaultFirebase, firebaseAuthConfig, AuthProviders, AuthMethods } from 'angularfire2';

@App({
  template: '<ion-nav [root]="rootPage"></ion-nav>',
  providers: [
    FIREBASE_PROVIDERS,
    defaultFirebase('https://samplequizapp-50eb5.firebaseio.com'),
    firebaseAuthConfig({
      provider: AuthProviders.Password,
      method: AuthMethods.Password
    })
  ],
  config: {} // http://ionicframework.com/docs/v2/api/config/Config/
})
export class MyApp {
  rootPage: any = HomePage;

  constructor(platform: Platform) {
    platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      StatusBar.styleDefault();
    });
  }
}

home.ts

import { Page } from 'ionic-angular';
import { AngularFire, FirebaseListObservable } from 'angularfire2';
import { OnInit } from '@angular/core'

@Page({
  templateUrl: 'build/pages/home/home.html'
})
export class HomePage implements OnInit {
  user: any = {};
  data: FirebaseListObservable<any[]>;

  constructor(private af: AngularFire) {
  }

  ngOnInit() {
    this.data = this.af.database.list('/userId')
  }

  signUp(data) {
    this.af.auth.createUser({
      email: data.email,
      password: data.password
    })
  }

}

I am pretty sure there is nothing wrong with my code:

回答1:

Firebase2 in its current version (2.4.2) is not yet compatible with Firebase SDK v3, and all projects created with the new Firebase console are only accessible with calls comaptible with SDK v3.

You want to create your Firebase backend in the legacy console www.firebase.com first, and then migrate to the new console.

This is documented in this closed issue of the angularfire2 github: https://github.com/angular/angularfire2/issues/189
