The page introduces react route

import React, { Component } from 'react'; import { Router, Route, IndexRoute, browserHistory } from 'react-router'; // 登录界面 import Login from '../Login/index'; class App extends Component { render() { return (    ); } } export default App;

But it keeps prompting an error, 'react-router' does not contain an export named 'browserHistory'.
My previous project used history={browserHistory}
How to modify this, are there any missing dependencies?
