我第一次、第二次和第三次尝试了这些教程，但骨干网仍然无法正常工作。控制台输出显示：“Uncaught TypeError: Cannot call method 'extend' of undefined”
文件夹结构为：
index.html
resources
js
b.js
main.js
meinmodul.js
libs
backbone.js
jquery-1.7.1.js
requireJS_2.1.5.js
underscore.js
索引.html：

alert('div foo is foo');
$('#foo').html('bar');
});
require(['jquery','backbone','b'], function(jq, Backbone, test) {
console.log("my backbone view");
});
b.js：
define(['jquery','backbone'], function($,Backbone) {
var SearchView = Backbone.View.extend({
events: {

console.log("init1");
console.log($('#testid'));

//return SearchView;
return {

我错过了什么或我做错了什么？
