  // Initialize Firebase

  firebase.analytics();

  export default firebase;

我的 firebase.js 文件位于 src 文件夹中，我收到上述错误。在将 firebase 导入我的 Register.js 时，我遇到了这个错误

【解决方案1】：

见https://firebase.google.com/docs/web/setup#using-module-bundlers

你应该添加import * as firebase from "firebase/app";

// Firebase App (the core Firebase SDK) is always required and must be listed first
import * as firebase from "firebase/app";

// If you enabled Analytics in your project, add the Firebase SDK for Analytics
import "firebase/analytics";

// Add the Firebase products that you want to use
import "firebase/auth";
import "firebase/firestore";

// TODO: Replace the following with your app's Firebase project configuration
const firebaseConfig = {
  // ...
};

// Initialize Firebase
firebase.initializeApp(firebaseConfig);
