Angular 火 2 错误 : The specified authentication provider is not enabled for this Firebase

Question

我正在使用 Ionic 2 和 angularfire 2 作为后端创建一个简单的示例身份验证应用程序，当我尝试创建新用户时，它说:

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

但我已经在 firebase 控制台中启用了 firebase 身份验证:

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
    })
  }

}

我很确定我的代码没有问题:

当前版本 (2.4.2) 中的 Firebase2 尚不兼容 Firebase SDK v3，使用新 Firebase 控制台创建的所有项目只能通过与 SDK v3 兼容的调用访问。

您想在旧控制台中创建 Firebase 后端 www.firebase.com首先，然后迁移到新控制台。

这记录在 angularfire2 github 的这个已关闭问题中:https://github.com/angular/angularfire2/issues/189
