javascript - 类型 'typeof import("/home/kartik/Desktop/Ecommerce/ecommerce/node_modules/firebase/index")' 上不存在属性 'auth'。ts(2339)

问题描述

我是 FireBase 的初学者，我正在尝试使用 Angular 使用 FireBase 实现 Google 登录。我在 auth 收到上述错误。我特此附上 package.json、package.lock.json 的 login.component.ts 和 dev 依赖项。

登录组件.ts

import { Component, OnInit } from '@angular/core';
import * as firebase from 'firebase';
import 'firebase/auth';
import {AngularFireAuth} from 'angularfire2/auth'

@Component({
  selector: 'app-login',
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit {

  constructor(private afAuth:AngularFireAuth) {
    firebase.default.database
   }

  ngOnInit(): void {
  }
  Login(){
    this.afAuth.auth.signInWithRedirect(new firebase.auth.GoogleAuthProvider()) //error due to this line.
  }

}

解决方案

您的依赖项是旧的。我建议您更新它们并使用新语法：

import { AngularFireAuth } from '@angular/fire/auth';
import { AngularFirestore } from '@angular/fire/firestore';
import { AngularFireDatabaseModule } from '@angular/fire/database';

import * as firebase from 'firebase/app';

和firebase@7.24.0

有关于firebase身份验证的完整教程，我觉得非常有用；这是链接

旧的进口是

import { AngularFireAuthModule } from 'angularfire2/auth';
