为什么我会收到错误

  

require.js：5未捕获错误：模块名称＆＃34;观看/音乐会/ ConcertView＆＃34;   尚未加载上下文：_

define(function (require) {
var $ = require('jquery'),
    Marionette = require('marionette'),
    WrapperView = require('views/WrapperView'),
    ConcertInfoAddView = require('views/concertInfo/ConcertInfoAddView'),

其ConcertView

define(function(require) {
var _ = require('underscore');
var Backbone = require('backbone'),
    Marionette = require('marionette'),

    },

    edit : function () {
        var concertModalView = ConcertView.getInfoModalView();
        concertModalView.setModel(this.model);
        $('#concertInfo-edit').modal('show');
    },

    delete : function () {
        var self = this;
        bootbox.confirm({
            size: 'small',
            message: "Are you sure?",
            callback: function(result){
                if(result){
                    self.model.destroy(null, {
                        success : function(model, response) {

                            });
                        },
                        error : function (model, response) {
                            if(_.isArray(response.responseJSON.notice)){

                                        type : response.responseJSON.type
                                    });
                                });
                            }else{
                                noty({

                                    type : response.responseJSON.type
                                });
                            }

                        }

                    });
                }
            }
        });

    },

    template : function(ops) {
        return _.template(Template)(ops);
    }

});

return ConcertInfoItemView;});

我需要它的地方，为什么错误？

我在这里尝试不要求，并在其他文件中要求，工作正常
