Ionic和Firebase中不存在firebase和auth属性

我正在使用ionic 5和firebase应用程序创建基于用户的内容和按钮显示。我正在通过帖子并在我的应用程序中实现它。

我和使用：
"firebase": "^8.1.1", "@angular/fire": "^6.1.3",

现在我在auth()和firestore()

身份验证错误是：类型“typeof import”（TS-2339）上不存在属性“auth”，并且 firebase 错误是 - 类型“typeof import”上不存在属性“firestore”

    import { Component, OnInit } from "@angular/core";
    import * as firebase from "firebase/app";
    import "firebase/auth";
    import "firebase/firestore";
     
    @Component({
      selector: "app-places",
      templateUrl: "./posts.page.html",
      styleUrls: ["./posts.page.scss"],
    })
    export class PlacesPage implements OnInit {
      constructor() {}
      //firestore = firebase.firestore();
      public isAdmin = false; 
      ngOnInit() {


    //Property 'auth' does not exist on type 'typeof import
            firebase.auth().onAuthStateChanged((user) => {
              if (user) {
                firebase


                  .firestore()    //Property 'firestore' does not exist on type 'typeof import
                 

 

    .doc(`s/${user.id}`)
                      .get()
                      .then((userProfileSnapshot) => {
                        this.isAdmin = userProfileSnapshot.data().isAdmin;
                      });
                  }
                });
       
        }
       }
