无法读取未定义的属性“ajax”

Question

请帮帮我，我正在使用以下代码：

index.js：

var $ =  require('./node_modules/jquery/dist/jquery.min');
var _ = require('./node_modules/underscore/underscore-min');
var Backbone = require('./node_modules/backbone/backbone-min');
require('./model/models');

run();

function run(){
    var session = new ****.***.Models.CustomerSession();
    session.save({
        "authenticators": ["********","****"]
    }).always(function(xhr){
        do_something...
    });
}

models.js：

**** = {};
****.*** = {};
****.***.Models = {};

var _ = require('../node_modules/underscore/underscore-min');
var Backbone = require('../node_modules/backbone/backbone-min');

/////////////MODELS/////////////

****.***.Models.CustomerSession = Backbone.Model.extend({
    urlRoot : 'https://*****.****.com/api/***/customer_session/'
});

****.***.Models.Transaction = Backbone.Model.extend({
    urlRoot : 'https://*****.****.com/api/***/transaction/'
});

****.***.Models.FaultType = Backbone.Model.extend({
    urlRoot : 'https://*****.****.com/api/***/fault_type/'
});

****.***.Models.FaultTypeSet = Backbone.Model.extend({
    urlRoot : 'https://*****.****.com/api/***/fault_type/'
});

****.***.Models.Task = Backbone.Model.extend({
    urlRoot : 'https://*****.****.com/api/***/task/'
});

并得到以下错误：“无法读取未定义的属性 'ajax'”... 这是项目中除 node_modules 库之外的所有代码... 我认为骨干无法识别 $ 符号，但我不确定也不知道如何处理这个问题...... 请帮助我...

这是我看到的错误日志：

这是使用主干代替主干分钟时的错误日志：

这被埋在上面的 cmets 中，但我遇到了同样的问题和设置

Backbone.$ = $
