jsx内でReact.createClassが使えないとエラーが出るので、使用できるようにしたい

const React = require('react');
const ReactDOM = require('react-dom');

var Foo = React.createClass({
    render(){
        return (<div>Foo</div>);
   },
});

ReactDOM.render(
	<Foo />,
	document.getElementById('example')
);

React.js初心者です。
現在手探り状態でローカル環境構築中で
上記のようにjsx内でテスト用として記述しました。
ただ、ターミナルで

component.jsx:17 Uncaught TypeError: React.createClass is not a function

と出ましたので色々調べたところ「create-react-class」のモジュールが必要とわかりましたので
それをインストールしようとしたところターミナルで以下のエラーがでました。

ちょっと解決方法がわからず皆様の落ちかを借りたいと思っております。。
また、以下にpackage.jsonも記述いたします。
