如何在index.js中配置react-router-dom，react-router-redux？

npm install react-router-dom react-router-redux

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import { Provider } from 'react-redux';
import { ConnectedRouter } from 'react-router-redux';
import { createBrowserHistory } from 'history';
import configureStore from './configureStore';
import App from './App';

const history = createBrowserHistory();
const store = configureStore(history);

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