TypeError: Object(...)不是函数。如何获得错误的解决方案？

Question

我想使用firebase.I运行我的react应用程序。我在visual studio Code程序中没有收到错误。但是在我的web浏览器中，applymiddaware(thunk.withextraargument ({getFirebase，getFirestore}))：TypeError: Object (...)给一个函数是错误的吗?我想知道解决方案是什么？

index.js

/* eslint-disable no-unused-vars */
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';

import {createStore, applyMiddleware,compose} from 'redux';
import rootReducer from './store/rootReducer';
import {Provider} from 'react-redux'
import thunk from 'redux-thunk'
import {getFirestore,reduxFirestore } from 'redux-firestore'
import {getFirebase,reactReduxFirebase} from 'react-redux-firebase'
import fbConfig from './config/fbConfig'

const store=createStore(rootReducer, 
    compose(
    applyMiddleware(thunk.withExtraArgument({getFirebase,getFirestore})),
    reduxFirestore(),
    reactReduxFirebase()
    )
    );

ReactDOM.render(<Provider store ={store}></Provider>><App />, document.getElementById('root'));

在您的package.json文件中，我看到您安装了react-redux-firebase的3.1.1版本，但您正在使用旧版本(Virsion2)的synthax创建存储。你必须要么将react-redux-firebase降级到版本2，要么按照v3迁移指南here创建你的商店。在过去的react-redux-firebase 2.2.4中使用了类似的synthax。
