【问题描述】：

通过此Full Stack React & Firebase Tutorial 并尝试使用 Firebase 身份验证来创建新用户，我收到以下错误。

教程详细代码如下：

// 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,
  ;

  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.error(err);
      return res.status(500).json( error: err.code );
    );
);

【参考方案1】：

根据here 的问答，我认为问题在于当我运行 Firebase@9 时，本教程包含 Firebase@8 的代码。

将 Firebase Admin SDK 文档引用到 Manage Users，我正在使用

const admin = require("firebase-admin");

而不是

const firebase = require("firebase");

我将代码更新为以下内容，现在可以在 POST 上成功添加用户。

// 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,
    phone: req.body.phone,
    name: req.body.name,
    photoURL: req.body.photo,
  ;

  admin
    .auth()
    .createUser(
      email: newUser.email,
      emailVerified: false,
      phoneNumber: newUser.phone,
      password: newUser.password,
      displayName: newUser.name,
      photoURL: newUser.photoURL,
      disabled: false,
    )
    .then((data) => 
      return res
        .status(201)
        .json( message: `user $data.uid signed up successfully` );
    )
    .catch((err) => 
      console.error(err);
      return res.status(500).json( error: err.code );
    );
);

【参考方案2】：

有了这些版本，它就可以工作了！！降级/升级这些依赖项以匹配

中的以下内容

"dependencies": 
"firebase": "^8.10.0",
"firebase-admin": "^8.13.0",
"firebase-functions": "^3.14.1"
,

【讨论】：

我不知道为什么，但它有效。

@ViacheslavDobromyslov 它可以工作，因为建议的答案是使用较旧的 Firebase SDK
