React路由器动态路由不呈现组件

我正在尝试通过以下示例来使路由器动态路由生效:https://github.com/rackt/react-router/tree/master/examples/huge-apps

这是我的设置:

webpack.config.js

module.exports = {
  devtool: 'inline-source-map',
  entry: './js/app.js',
  output: {
    path: '../public',
    filename: 'test-app.js',
    chunkFilename: '[id].chunk.js',
    publicPath: '/public/'
  },
  module: {
    loaders: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel',
        query: {
          presets: [
            'es2015',
            'react'
          ]
        }
      }
    ]
  }

./js/app.js

import React from 'react';
import ReactDOM from 'react-dom';
import { createHistory, useBasename } from 'history';
import { Router } from 'react-router';

const history = useBasename(createHistory)({
  basename: '/'
});

const rootRoute = {
  component: 'div',
  childRoutes: [{
    path: '/',
    component: require('./components/App')
  }]
};

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

./components/App.js

import React from 'react';

console.log('testing');

export default class App extends React.Component {
  render() {
    console.log('App');
    return (
        <div>
          App!
        </div>
    )
  }
}

index.html

<!doctype html>
<html>
    <head>
        <title>Test App</title>
    </head>
    <body>
        Hello
        <div id="root"></div>
        <script src="public/test-app.js"></script>
    </body>
</html>

当我运行服务器时,我看到index.html显示 Hello ,我也看到来自console.log('testing')的{​​{1}},但实际App.js组件不呈现。有什么想法吗?

谢谢!

修改 如果我将App.js更改为下面的ES5语法,它就可以了!这是为什么?路由器./components/App.js的反应是否与ES6不兼容?

component: require('./components/App')

我认为,您使用的是Babel 6,它们changed commonjs require语法。

现在,您需要添加default

component: require('./components/App').default

我遇到了同样的问题,终于找到了如何使它发挥作用。
