【问题描述】：

根据我编写的代码的文档，我正在使用 react-firebaseui 进行身份验证

import React from "react";
import StyledFirebaseAuth from "react-firebaseui/StyledFirebaseAuth";
import firebase from "firebase";

const firebaseConfig = {
  ...
};
// Initialize Firebase
firebase.initializeApp(firebaseConfig);


// Configure FirebaseUI.
const uiConfig = {
  // Popup signin flow rather than redirect flow.
  signInFlow: "popup",
  // Redirect to /signedIn after sign in is successful. Alternatively you can provide a callbacks.signInSuccess function.
  //   signInSuccessUrl: '/signedIn',
  // We will display Google and Facebook as auth providers.
  signInOptions: [firebase.auth.GoogleAuthProvider.PROVIDER_ID],
};

export const SignInWith = () => (
<>
    <p>Login</p>
    <StyledFirebaseAuth uiConfig={uiConfig} firebaseAuth={firebase.auth()} />
</>
);

但我不断收到此错误

./node_modules/firebaseui/dist/esm.js
尝试导入错误：“app”未从“firebase/app”导出（导入为“firebase”）。`.

我尝试使用 import firebase from 'firebase/app 导入 firebase，但仍然出现同样的错误。我尝试评论 StyledFirebaseAuth 导入和标记并且它正在工作，所以我确定问题出在 react-firebaseui 上。这是我的 package.json

{

感谢您的帮助。

【问题讨论】：

请编辑问题以显示您的 package.json。每个库的版本都很重要。如果您最近更改了某些内容，请说出那是什么。
我认为你需要在react-firebase之前导入firebase。你能检查一下吗？
@ShubhamVerma 我尝试在 react-firebaseui 之前导入 firebase，但仍然出现错误，导入也是文档中的内容。

标签： reactjs firebase firebaseui

【解决方案1】：

不幸的是，您已将“firebase”依赖项升级到 8.0.0，但“firebaseui”依赖项尚不支持它。在 firebaseui 和 react-firebaseui 支持 breaking changes in 8.0.0 之前，您必须暂时将 firebase 降级到版本 7.24.0。

【讨论】：

没有其他的走走

【解决方案2】：

import firebase随着9.0.0版本的变化，现在有兼容性不需要降级，所以你可以在你的imports中使用/compat文件夹，

import firebase from 'firebase/compat/app'
