我一直在使用 react-redux-firebase 进行一个项目，该项目以前对我有用。今天我收到以下错误：

我不确定错误是否在我的代码中的其他地方，或者我是否必须将 react-redux-firebase 更新到版本 3. . ，目前似乎不存在。其他人遇到过这个问题吗？我将不胜感激任何建议。

这是我的 package.json 中的依赖项：

"dependencies": { "firebase": "^5.7.0", "react": "^16.6.3", "react-dom": "^16.6.3", "react-redux": "^6.0.0", "react-redux-firebase": "^2.2.5", "react-router-dom": "^4.3.1", "react-scripts": "2.1.1", "redux": "^4.0.1", "redux-firestore": "^0.6.0", "redux-thunk": "^2.3.0" },

这是我的 index.js 文件的样子：

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
import { 
  createStore, 
  applyMiddleware, 
  compose 
} from 'redux';
import rootReducer from './store/reducers/index';
import { Provider } from 'react-redux';
import thunk from 'redux-thunk';
import { reduxFirestore, getFirestore } from 'redux-firestore';
import { reactReduxFirebase, getFirebase } from 'react-redux-firebase';
import fbConfig from './firebase/fbConfig';

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

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


serviceWorker.unregister();
