backbone.js - Problems loading backbonejs and underscorejs with requirejs -


i have problems loading libraries shim option in requirejs (maybe, because poor background on library). try in documentation , see other pages problem persist.

this app folder structure:

index.html js/main.js js/app/router.js js/app/app.js js/views/homeview.js js/libs/backbone/backbone-1.0.0.js js/libs/underscore/underscore-1.5.1.js js/libs/jquery/jquery-1.10.2.js js/libs/require/require-2.1.8.js

all start in index.html:

    <!doctype html>     <html>         <head>         <meta charset="utf-8" />         <meta name="format-detection" content="telephone=no" />         <meta name="viewport" content="width=device-width, user-scalable=no" />         <link rel="stylesheet" type="text/css" href="css/index.css" />         <title>app</title>     </head>     <body>         <div class="page">             loading...         </div>         <script data-main="js/main" src="js/libs/require/require-2.1.8.js"></script>     </body> </html>

that loads main.js

require.config({     shim: {         underscore: {             exports: '_'         },         backbone: {             deps: ['underscore', 'jquery'],             exports: 'backbone'         },     },     paths: {         app:        'app',         mod:        'app/mods',         backbone:   'libs/backbone/backbone-1.0.0',         underscore: 'libs/underscore/underscore-1.5.1',         jquery:     'libs/jquery/jquery-1.10.2',       }, });  require([     'app/app', ], function (app) {     app.initialize(); });

that defines paths libraries , shim options non-amd libraries.

then comes app.js

define([         'app/router', ], function(router) {     var initialize = function() {         //var router = new router();         //router.initialize();             router.initialize();     };      return {         initialize: initialize,     }; });

then router.js:

define([         'jquery',         'underscore',         'backbone',         'app/views/homeview', ], function($, _, backbone, homeview) {     var approuter = backbone.router.extend({         routes: {             '': 'home',         }     });      var initialize = function() {         var approuter = new approuter();         var homeview = new homeview();          approuter.on('route:home', function() {             userlistview.render();             console.log('we have loaded home page.');         });          backbone.history.start();     };      return {         initialize: initialize,          }; });

now here have problem beacause looking @ network tab in chrome developer tools jquery loads, nor backbone or underscore.

then, , finally, because it's defined reference view, loads homeview.js

define([         'jquery',         'underscore',         'backbone',         'libs/text!app/tpl/home.html', ], function($, _, backbone, hometpl) {     var homeview = backbone.view.extend({         el: '.page',         render: function() {             //var self = this;             //users.fetch({             //  success: function() {                     var template = _.template(hometpl, {});                     //self.$el.html(template);                                       this.$el.html(template);             //  }             //});         },     });       return homeview; });

and problem, because @ line 

var homeview = backbone.view.extend({
shows error: "uncaught typeerror: cannot read property 'view' of undefined", think that's because backbone never loads.

¿can tell i'm doing terribly wrong? looking code , several pages day , cannot figure out answer. in advance , apoliges long question, buy i've seen many people having same issue , maybe answer others too.

can't find wrong, don't need load app modules in paths

paths: {   app: 'app', // remove
