页面引入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 (
            <Router history={browserHistory}>
                <Route path="/login" component={Login} />
            </Router>
        );
    }
}

export default App;

但是一直提示报错，'react-router' does not contain an export named 'browserHistory'.
我之前的项目使用history={browserHistory}
请问下这个怎么修改，少了什么依赖吗
