如何解决react-router4 link点击url在之前的url追加的问题?

Question

点击首页，然后点击版本检测，此时都是正常跳转，看地址栏，然后再点首页，为什么地址变成http://localhost:3000/#/install/update/erp，怎么在版本检测的url上进行追加，不应该是http://localhost:3000/#/erp ???

怎么解决这个问题?

class Routes extends Component {

    render() {
        return(
            <Router>
                <Switch>
                    {config.map((route, index) => (
                        !route.private ? (
                            <Route
                                key={index}
                                path={route.path}
                                exact={route.exact}
                                component={route.component}
                            />
                        ) : (
                            <PrivateRoute
                                key={index}
                                path={route.path}
                                exact={route.exact}
                                component={route.component}
                            />
                            )

                    ))}
                    <Route render={ () => {
                        return (<p></p>)
                    } }/>
                </Switch>
            </Router>
        )
    }
}

import WrappedNormalLoginForm  from '../login/login'
import TableComponent from '../component/tableComponent';
import Page from '../menu/page'

export const config = [
    {
        path: '/',
        exact: true,
