有人能帮我写这段代码吗？我正在尝试用React和firebase认证做一个网站项目。当我尝试运行这段代码时，React显示一个错误=〉Module not found：错误：未从包中导出包路径

import firebase from "firebase";

const firebaseConfig = {
  apiKey: "...",
  authDomain: "...",
  projectId: "...",
  storageBucket: "...",
  messagingSenderId: "...",
  appId: "...",
  measurementId: "..."
};

const firebaseApp = firebase.initializeApp(firebaseConfig);
const db = firebaseApp.firestore();
const auth = firebase.auth();
const provider = new firebase.auth.GoogleAuthProvider();
const storage = firebase.storage();

export { auth, provider, storage };
export default db;

我已经多次尝试更改import语句，但没有效果
