Keep Getting Use Require Error

[patvin80]

Module name "twitter-node-client" has not been loaded yet for context: _. Use require([])

I am trying to use this in a Office 365 Addin and followed the instructions.

(function(){
  'use strict';

  // The Office initialize function must be run each time a new page is loaded
  Office.initialize = function(reason){
    jQuery(document).ready(function(){
      app.initialize();

      displayItemDetails();
    });
  };

  // Displays the "Subject" and "From" fields, based on the current mail item
  function displayItemDetails(){
    var item = Office.cast.item.toItemRead(Office.context.mailbox.item);
    jQuery('#subject').text(item.subject);

    var from;
    if (item.itemType === Office.MailboxEnums.ItemType.Message) {
      from = Office.cast.item.toMessageRead(item).from;
    } else if (item.itemType === Office.MailboxEnums.ItemType.Appointment) {
      from = Office.cast.item.toAppointmentRead(item).organizer;
    }

    if (from) {
      jQuery('#from').text(from.displayName);
      jQuery('#from').click(function(){
        app.showNotification(from.displayName, from.emailAddress);
      });
    }
     debugger;
      //Callback functions 
    var error = function (err, response, body) {
        console.log('ERROR [%s]', err);
    };
    var success = function (data) {
        console.log('Data [%s]', data);
    };

    var Twitter = require('twitter-node-client').Twitter;

    //Get this data from your twitter apps dashboard 
    var config = {
        "consumerKey": "z3qgwIah7X8dWA8O2ktwqQ",
        "consumerSecret": "j8f3g03UImTrl2wb0aUvS7Qj062PmHGHNoBix1VmYgYm",
        "accessToken": "18077593-47K5rni1FLI9DmHlKEIW9tYSPHCaWpGNZ8U",
        "accessTokenSecret": "EohjUdkNWx4fHcNYlklKYnTu5j0rNY3VAnmjLIq "
    }

    var twitter = new Twitter(config);

      twitter.getSearch({'q':'#haiku','count': 10}, error, success);
      twitter.getSearch({'q':'#haiku','count': 10}, error, success);
  }
})();
