React-router 链接不起作用

React-router 的起步非常糟糕......看起来基本的东西不起作用。使用react-router 2.0.0我的Link组件将URL更新为/about，但我的页面在那之后不会渲染About组件......

入口点js

var React = require('react');
var ReactDOM = require('react-dom');
var Router = require('react-router').Router;
var Route = require('react-router').Route;
var hashHistory = require('react-router').hashHistory;
var App = require('./components/App.react');
var About = require('./components/About');

ReactDOM.render(
    <Router history={hashHistory} >
        <Route path="/" component={App}>
            <Route path="about" component={About} />
        </Route>
    </Router>, 
    document.getElementById('app')
);

App.js

'use strict';

var React = require('react');
var Link = require('react-router').Link;
var Header = require('./Header');
var UserPanel = require('./UserPanel');
var ModelPanel = require('./ModelPanel.react');
var EventPanel = require('./event/EventPanel');
var VisPanel = require('./vis/VisPanel');
var LoginForm = require('./LoginForm');
var AppStore = require('../stores/AppStore');
var AppStates = require('../constants/AppStates');

var App = React.createClass({

  [... code omitted ...]

  render: function() {
    var viewStateUi = getViewStateUi(this.state.appState);

    return (
      <div>
        <Header />
        <Link to="/about">About</Link>
        {viewStateUi}
      </div>
    );
  }

});

由于某种原因，<Link>以下配置不适用于我。

// 索引.js

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

// 应用程序.js

  return (
      <div className="App">
        <Route exact={true} path="/:lang" component={Home} />
        <Route exact={true} path="/" render={() => <Redirect to={{ pathname: 'pt' }} />} />
        <Route path="/:lang/play" component={Play} />} />
        <Route path="/:lang/end" component={End} />
      </div >
    );

主页组件具有链接，但应用程序上的链接也会执行相同的操作。每次我点击它时，它只会改变网址，但视图会保持不变。

当我添加时我能够让它工作带路由器到 App.js

export default withRouter(connect(mapStateToProps, { f, g })(App));

我还是不明白发生了什么事。也许它与 redux 有关，或者我遗漏了一些细节。
