I'm currently learning react-router, and then trying to implement it in a sample app.
我目前正在学习 react-router，然后尝试在示例应用程序中实现它。
Here is my code:

我使用gulp到browserify和reactify我的消息来源成/dist/js/main.js
When I click on my aboutlink, url changes from http://localhost:8000/#/?_k=zkmiyhto http://localhost:8000/#/about?_k=6nhkaoyet the displayed component is still hello-world.
当我点击我的about链接时，url 会从http://localhost:8000/#/?_k=zkmiyh变为 ，http://localhost:8000/#/about?_k=6nhkao但显示的组件仍然是hello-world。
There is no error displayed on my console.
我的控制台上没有显示错误。
Is there something missing out?
有什么遗漏吗？

The uglysolution is to get rid of nested routeslike so:
该丑陋的解决办法是摆脱嵌套的路线，像这样：
module.exports = (
<Router>
<Route path="/" component={HelloWorld} />
<Route path="/about" component={About} />
</Router>
);
Yet, I figured it out the right way to dovia this doc
然而，我通过这个文档找到了正确的方法
We need another component (which I called Main) that will contain the right component to display (i.e. this.props.children).
我们需要另一个组件（我称之为Main），它将包含要显示的正确组件（即this.props.children）。
I use IndexRouteto define the defaultcomponent to display.
我IndexRoute用来定义要显示的默认组件。
Here is the corrected code:
这是更正后的代码：
/src/components/main.jsx (new)
/src/components/main.jsx（新）
var React = require('react');
module.exports = React.createClass({
render: function() {
return <div>
// this is where you can add header
{this.props.children}
// this is where you can add footer
</div>
}
});
/src/routes.jsx (modified)
/src/routes.jsx（修改）
var React = require('react');
var Router = require('react-router').Router;
var Route = require('react-router').Route;
var IndexRoute = require('react-router').IndexRoute;
var Main = require('./components/main');
var HelloWorld = require('./components/hello-world');
var About = require('./components/about');
module.exports = (
<Router>
<Route path="/" component={Main}>
<IndexRoute component={HelloWorld} />
<Route path="about" component={About} />
</Route>
</Router>
);

I have also same prob in my APP I have changed parent and set as same node then it's working may be it may help you
我在我的 APP 中也有同样的问题我已经改变了父节点并设置为相同的节点然后它正在工作可能会帮助你
module.exports = (
<Router>
<Route path="/" component={HelloWorld} />
<Route path="about" component={About}/>
</Router>
);
);
