使用router4無法實(shí)現(xiàn)跳轉(zhuǎn)怎么解決？

import React from 'react'
import {
    BrowserRouter,
    Route,
    Link,
    hashHistory,
    Switch
} from 'react-router-dom'

import About from './About';
import Repos from './Repos';
import App from './App';

const BasicRouter = () => (
    <BrowserRouter>
        <div>
            <Route path="/" component={App}/>
            <Route path="/repos" component={Repos}/>
            <Route path="/about" component={About}/>
        </div>
    </BrowserRouter>
)

export default BasicRouter
