【问题描述】：

我想用 firebase 运行我的 react 应用程序。我在 Visual Studio 代码程序中没有收到错误消息。但在我的网络浏览器中，applymiddaware(thunk.withextraargument ({getFirebase,getFirestore})) : TypeError: Object (...) is given a function error.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'));

标签： reactjs firebase redux google-cloud-firestore

【解决方案1】：

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的 synthax（virsion 2）创建商店。您必须将 react-redux-firebase 降级到版本 2，或者按照 v3 迁移指南 here 创建您的商店。过去在 react-redux-firebase 2.2.4 中使用过类似的合成器。

【讨论】：

TypeError: Cannot read property 'SDK_VERSION' of undefined. 我照你说的做了，但他犯了一个错误。
试试这两个 virsions 像这样： npm i --save react-redux@5.1.1 react-redux-firebase@2.2.4 ，如果还有其他问题，检查你正在使用的 virsions是兼容的。
