我正在学习编写云函数的教程，我尝试导入 firebase 并使用教程中使用的 firebase.auth()，但出现以下错误。

代码

函数/index.js

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const app = require('express')();

admin.initializeApp();

const config = {
  apiKey: 'AIzaSyDMFe1IwnLoui-Meue-FMwNhc1k-MB8vc8',
  authDomain: 'socialape-d306c.firebaseapp.com',
  projectId: 'socialape-d306c',
  storageBucket: 'socialape-d306c.appspot.com',
  messagingSenderId: '705972174784',
  appId: '1:705972174784:web:1ed87302a774bd1cef1225',
};

const firebase = require('firebase');
firebase.initializeApp(config);

// Signup route

app.post('/signup', (req, res) => {
  const newUser = {
    email: req.body.email,
    password: req.body.password,
    confirmPassword: req.body.confirmPassword,
    handle: req.body.handle,
  };
  // TODO: validate date

  firebase
    .auth()
    .createUserWithEmailAndPassword(newUser.email, newUser.password)
    .then((data) => {
      return res
        .status(201)
        .json({ message: `user ${data.user.uid} signed up successfully` });
    })
    .catch((err) => {
      console.log(err);
      return res.status(500).json({ error: err.code });
    });
});

// To tell firebase cloud functions to use routes on express app
// we have written api because we want all our API URL's to start with /api.

exports.api = functions.https.onRequest(app);

我知道由于版本更改（本教程从 2019 年开始），导入可能会略有不同，但我无法修复它。请帮帮我

【解决方案1】：

您应该在云函数而不是客户端中使用 Admin SDK。话虽如此，您可以删除const firebase = require("firebase") 和firebase.initializeApp(config); 以及客户端配置。创建用户可以使用createUser()方法：

app.post('/signup', (req, res) => {
  const newUser = {
    email: req.body.email,
    password: req.body.password,
    confirmPassword: req.body.confirmPassword,
    handle: req.body.handle,
  };

  return admin.auth().createUser({ email, password }).then((userRecord) => {
    return res.send(`Created user ${userRecord.uid}`)
  })
}

我不确定“句柄”是什么，但您可以使用 Custom Claims 或任何数据库来存储它。

请注意，在云功能或服务器环境中创建用户不会自动让用户登录。返回响应后，您必须将用户重定向到您的登录页面。
