TypeError：无法设置属性＆＃39; fullCalendar＆＃39;未定义的

Question

您好我使用fullCalendar jQuery插件使用以下反应组件：

import React from 'react';
import $ from 'jquery';
import moment from 'moment';
import fullCalendar from 'fullcalendar';

class calendarApp extends React.Component {
    componentDidMount(){
    $('#calendar').fullCalendar({
            defaultDate: '2014-09-12',
            editable: true,
            eventLimit: true,
     });
  }  render(){
      return(
         <div id="calendar">
         </div>
      );
    }
}

export default calendarApp;

我收到以下错误：

C:\Users\syedj\Desktop\newScheduler\node_modules\fullcalendar\dist\fullcalendar.js:28
$.fn.fullCalendar = function(options) {
                  ^

我已经通过npm安装了jquery，moment和full calendar。我仍然不明白为什么我得到错误。非常感谢任何帮助，谢谢。
