title: React Router no input file specified
body: <p>I'm using react-router to navigate my page to auth page. Here is my code:</p>
  
  <pre><code>import React, {Component} from 'react';
  import ReactDOM from 'react-dom';
  import {Provider} from 'react-redux';
  import {createStore, applyMiddleware} from 'redux';
  import {Router, Route, IndexRoute, browserHistory} from 'react-router';
  import reducers from './reducers';
  
  import App from './components/app';
  import Authenticate from './components/auth/index';
  import Login from './components/auth/login';
  
  ReactDOM.render(
      &lt;Provider store={createStoreWithMiddleware(reducers)}&gt;
          &lt;Router history={browserHistory}&gt;
              &lt;Route path="authenticate"&gt;
                  &lt;IndexRoute component={Login} /&gt;
                  &lt;Route path="/login" component={Login}/&gt;
              &lt;/Route&gt;
              &lt;Route path="/" component={App}&gt;
                  &lt;IndexRoute component={Login} /&gt;
              &lt;/Route&gt;
          &lt;/Router&gt;
      &lt;/Provider&gt;
      , document.querySelector('.container')
  );
  ReactDOM.render(
      &lt;Provider store={createStoreWithMiddleware(reducers)}&gt;
          &lt;Router history={browserHistory}&gt;
              &lt;Route path="/authenticate" component={Authenticate}&gt;
                  &lt;IndexRoute component={Login} /&gt;
                  &lt;Route path="login" component={Login}/&gt;
              &lt;/Route&gt;
              &lt;Route path="/" component={App}&gt;
  
              &lt;/Route&gt;
          &lt;/Router&gt;
      &lt;/Provider&gt;
      , document.querySelector('.container')
  );
  </code></pre>
  
  <p>The problem is every time I navigate to <code>authenticate/login</code> it always say <code>No input file specified.</code>. But if I navigate to <code>/</code> it works properly</p>
  
  <p>Any solution?</p>
