問題：Firebase：未啟用 Firebase 應用程式'[DEFAULT]' - 請呼電 Firebase App.initializeApp() (app-compat/no-app)

Question

我正在练习制作一些使用ReactJS的项目，但当我将配置文件保存如下时，它将错误显示为标题。有人遇到过这种麻烦吗？请帮帮我！谢谢

import { initializeApp } from "firebase/app";
import { getAnalytics } from "firebase/analytics";
import firebase from 'firebase/compat/app';
import 'firebase/analytics';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';
// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries
// Your web app's Firebase configuration
// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
apiKey: "AIzaSyD0rxJTIV4RIKfdFJB6G--9md2-SAEDwjs",
authDomain: "chat-app-d3f09.firebaseapp.com",
projectId: "chat-app-d3f09",
storageBucket: "chat-app-d3f09.appspot.com",
messagingSenderId: "361125159681",
appId: "1:361125159681:web:9557ff40c4e38e30ba3100",
measurementId: "G-X1Q63CL2N2"
};
// Initialize Firebase
const app = initializeApp(firebaseConfig);
const analytics = getAnalytics(app);
const auth = firebase.auth();
const db = firebase.firestore();
export { db, auth }
export default firebase

Answer 1

您使用的是带有8&gt；。

尝试：

const app = initializeApp(firebaseConfig);
const analytics = getAnalytics(app);
//const auth = firebase.auth();
const auth = getAuth(app)
//const db = firebase.firestore();
const db = getFirestore(app)

或者如果你想使用版本8&gt；然后：

const app = firebase.initializeApp(firebaseConfig);
//const analytics = getAnalytics(app);
const auth = firebase.auth();
const db = firebase.firestore();

请注意，firebase版本9+是以函数方式编写的。
