Firebase始终返回该电子邮件已注册

Question

我已将this的基础知识应用到我的应用程序中，但我遇到的问题是它总是返回一个错误，指出用户已经在空的firebase上注册了电子邮件。

这是注册用户的功能：

registerUser()
{
    if (this.newUser.password === this.newUser.passwordConfirm)
    {
        this.firebaseRef.createUser({email: this.newUser.email, password: this.newUser.password}, (error) => {
            if (error) {
                console.log(error);
            }
        });
    }
    else
    {
        console.log("Invalid passwords");
    }

}

并且始终返回此错误：user-registration.component.ts:34 Error: The specified email address is already in use.(…)。就像我说的，firebase是空的，我100％确定我用正确的URL初始化了firebase

这是我在Angular2中的注册组件

import { Component, OnInit} from '@angular/core';
import {FirebaseEventPipe} from "../firebasepipe";
import {User} from "../classes/user";



@Component({
    selector: 'registration',
    templateUrl: 'app/views/registration.component.html',
    pipes: [FirebaseEventPipe],

})

export class RegistrationComponent implements OnInit{

    private firebaseUrl: string;
    private firebaseRef: Firebase;

    newUser: User;

    submitted = false;

    constructor() {
        this.firebaseUrl = "https://<<myfirebaseurl>>.firebaseio.com/";
        this.firebaseRef = new Firebase(this.firebaseUrl);
    }

    registerUser()
    {
        if (this.newUser.password === this.newUser.passwordConfirm)
        {
            this.firebaseRef.createUser({email: this.newUser.email, password: this.newUser.password}, (error) => {
                if (error) {
                    console.log(error);
                }
            });
        }
        else
        {
            console.log("Invalid passwords");
        }

    }

    ngOnInit():any {
        this.newUser = {email: '', password: '', passwordConfirm: ''}
    }

    // TODO: Remove this when we're done
    get diagnostic() { return JSON.stringify(this.newUser); }
}
