错误 [ERR_PACKAGE_PATH_NOT_EXPORTED]：没有“出口” - Firebase

Question

通过此全栈 React 和 Firebase 教程并尝试使用 Firebase 身份验证来创建新用户，我收到以下错误。

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in /socialapp-functions/functions/node_modules/firebase/package.json

本教程详细代码如下：

// 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 });
    });
});

Answer 1

根据这里的问题和答案，我认为问题在于当我运行 Firebase@9 时，本教程有 Firebase@8 的代码。

引用 Firebase Admin SDK 文档来管理用户，我正在使用

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

代替

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 });
    });
});

Answer 2

使用这些版本，它可以工作！ 降级/升级这些依赖项以匹配 <package.json> 中的以下内容

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

Answer 3

只需在您的 node_modules 中安装xhr2 ，然后使用 firebase -admin而不是 firebase 然后尝试。

Answer 4

2022 年 6 月

在节点 js

我所有问题的永久解决方案是卸载 firebase v9+

接下来我做了：

npm uninstall firebase

然后

npm i firebase@8.6.8

希望这也能解决您的问题

编辑：在此之后你也不需要 firebase-admin

Answer 5

使用 Firebase SDK 执行此操作的方式已随新版本 9更改。

代替

const firebase = require("firebase");

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

做这个

const { getAuth, createUserWithEmailAndPassword } = require( "firebase/auth");

const auth = getAuth();
createUserWithEmailAndPassword(auth, email, password)
.then((data) => {
  return res
    .status(201)
    .json({ message: `user ${data.user.uid} signed up successfully` });
})
