paths中已经引入模块了。。
'datepicker' : '/assets/javascript/static/libs/datetimepicker/bootstrap-datetimepicker.min',
'timepicker' : '/assets/javascript/static/libs/timepicker/timepicker',

require(['moment', 'jquery', 'underscore', 'backbone', 'mustcach', 'nprogress', 'highcharts', 'datepicker','timepicker'],

function(moment, $, _, b, mustcach, NProgress, highcharts, datepicker, timepicker) {

$("#start_time").DateTimePicker({

format:'yyyy-mm-dd hh:ii'

});
}

运行结果显示方法 DateTimePicker未定义
