kadira_react-layout.js未捕获的TypeError：React.render不是函数

Question

我现在正在尝试Meteor和React。当我运行应用程序时，它会显示一个空白页面。我检查了控制台，发现错误。我不知道这是不是它的原因。请帮助。

Layout = React.createClass({
        render(){
            return(
                <div className="wrapper">
                    <div className="box">
                        <div className="srow row-offcanvas row-offcanvas-left push-down-50">
                            NavBar
                            {this.props.sidebar}
                            {this.props.content}
                        </div>
                    </div>
                </div>
            )
        }
    });
