auth.createUserWithEmailAndPassword不是函数

我有以下设置来连接到Firebase，但是由于某种原因，在浏览器控制台中它显示auth.createUserWithEmailAndPassword()不是一个函数。我的代码有问题吗？

        import { initializeApp } from 'https://www.gstatic.com/firebasejs/9.0.2/firebase-app.js';
        import { getAuth, createUserWithEmailAndPassword } from 'https://www.gstatic.com/firebasejs/9.0.2/firebase-auth.js';
        import { getFirestore } from "https://www.gstatic.com/firebasejs/9.0.2/firebase-firestore.js"

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

        const app = initializeApp(firebaseConfig);
        const auth = getAuth();
        const db = getFirestore();

        var button = document.getElementById("button").addEventListener("click", function () {
            var email = document.getElementById("email").value;
            var phone = document.getElementById("phone").value;
            var password = document.getElementById("password").value;

            auth.createUserWithEmailAndPassword(email, password).then(cred => {
                console.log(cred);
            })
        });

编辑：我从auth.createUserWithEmailAndPassword(email, password).then(cred => { console.log(cred);中删除了auth.，现在它给出了当前错误：`Uncatch(In Promise)TypeError：Cannot Create Property 字符串‘heheboi@gmail.com’上的‘_canInitEmulator’

解决方案

只需将您的代码更新到最新的Firebase SDK9：

import { initializeApp } from 'https://www.gstatic.com/firebasejs/9.0.2/firebase-app.js';
import { getAuth, createUserWithEmailAndPassword } from 'https://www.gstatic.com/firebasejs/9.0.2/firebase-auth.js';
import { getFirestore } from "https://www.gstatic.com/firebasejs/9.0.2/firebase-firestore.js"

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

const app = initializeApp(firebaseConfig);
const auth = getAuth();
const db = getFirestore();

var button = document.getElementById("button").addEventListener("click", function () {
    var email = document.getElementById("email").value;
    var phone = document.getElementById("phone").value;
    var password = document.getElementById("password").value;

    createUserWithEmailAndPassword(auth, email, password).then(cred => {
        console.log(cred);
    }).catch((error) => {
      const errorCode = error.code;
      const errorMessage = error.message;
      // ..
    });
});

您已经在导入createUserWithEmailAndPassword。您不能再使用auth.createUserWithEmailAndPassword。您可以找到here最新文档。
