将jsx转换为js后dom未定义错误

我创建了一个jsx文件，如下所示

  /** @jsx dom */
(function(){
'use strict';

define([
        'jquery',
        'react',
        'react-dom'
    ],

    function($, React, ReactDOM){

        var AppView = React.createClass({
            render: function() {
                return <div>Hello World</div>;
            }
        });

        ReactDOM.render(<AppView />, document.getElementById('dsl-application'));

    });
})();

并使用以下命令将jsx转换为js

babel --watch src --out-dir bundle --preset react

和输出文件如下

(function () {
'use strict';

define(['jquery', 'react', 'react-dom'], function ($, React, ReactDOM) {

    var AppView = React.createClass({
        displayName: 'AppView',

        render: function () {
            return dom(
                'div',
                null,
                'Hello World'
            );
        }
    });


    ReactDOM.render(dom(AppView, null), document.getElementById('dsl-application'));
});
})();

问题是我遇到了Uncaught ReferenceError：在浏览器中运行js文件时未定义dom的问题。转换后添加dom。任何线索如何解决这个问题？

要将 JSX 在浏览器中转换为 JS，您需要browser.js从babel. 有关简单示例，请参阅https://github.com/ruanyf/react-demos/blob/master/demo01/index.html

[[根据更多信息更新]]

使用以下文件，然后运行npm install和webpack，然后您的index.html服务就可以使用了。

索引.html

<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    <div id="example"></div>

    <script type="text/javascript" src="bundle.js" charset="utf-8"></script>
  </body>
</html>
