【问题描述】：

我确定我在这里遗漏了一些简单的东西，但无法正确配置我的路线。

我得到这个错误：

Warning: Failed prop type: The prop 'children' is marked as required in 'App', but its value is 'undefined'. in App (created by RouterContext) in RouterContext (created by Router) in Router

这是我的基本设置：

./index.jsx

import React from 'react';
import ReactDOM from 'react-dom';
import {Router, browserHistory} from 'react-router';
import routes from './routes';

ReactDOM.render(
  <Router history={browserHistory} routes={routes}/>, document.getElementById('root'));

./routes/index.js

module.exports = {
  path: '/',
  component: require('../components/app'),
  indexRoute: require('./home')
};

./routes/home.js

module.exports = {
  getComponent(nextState, cb) {
    require.ensure([], (require) => {
      cb(null, require('../components/home'));
    });
  }
};

./components/app/index.jsx

import React, {PropTypes} from 'react';

const App = props => (
  <section>
    <h1>My App</h1>
    <section>{props.children}</section>
  </section>
);

App.propTypes = {
  children: PropTypes.node.isRequired
};

export default App;

./components/home/index.jsx

import React from 'react';

const Home = () => (
  <section>
    <h3>Home</h3>
  </section>
);

export default Home;

【解决方案1】：

需要使用导出的文件时需要指定.default。没有它 Home 将是未定义的，因此会出现错误

./routes/home.js

module.exports = {
    getComponent(nextState, cb) {
        require.ensure([], (require) => {

        // need to specify .default when requiring a file using export
        cb(null, require('../components/home').default);
        });
    }
};
