Marionette.Application() has no Method initRegionManager - requirejs

Question

im struggling with a weird Issue with Backbone.Marionette an requireJS.
RquireJS is configured like https://github.com/marionettejs/backbone.marionette/wiki/Using-marionette-with-requirejs says:
require.config({
deps: ['main'],
paths : {
backbone : '../vendor/backbone.marionette/backbone',
underscore : '../vendor/underscore/underscore',
jquery : '../vendor/jquery/jquery',
marionette : '../vendor/backbone.marionette/backbone.marionette.min'
},
shim : {
jquery : {
exports : 'jQuery'
},
underscore : {
exports : '_'
},
backbone : {
deps : ['jquery', 'underscore'],
exports : 'Backbone'
},
marionette : {
deps : ['jquery', 'underscore', 'backbone'],
exports : 'Marionette'
}
}
});
The main.js:
require([
'app'
],
function(App) {
App.start();
}
);
And the app.js:
define([
'marionette'
],
function(Marionette) {
var app = Marionette.Application();
return app;
}
);
But when I wanna start a Application my Console says:
Uncaught TypeError: Object #<Object> has no method '_initRegionManager'
I did nothing special so far:
define(
[
'marionette'
],
function(Marionette) {
"use strict";
var app = Marionette.Application();
// app.on('initialize:after', function() {
// console.log("Initialize:After");
// });
return app;
}
);
And in the main.js (Startingpoint) i require the code above and wanna start it.
But it fails at Marionette.Application();
When i look into the marionette.js i can clearly see underscore extending the Application with the _initRegionManager-Method. Also in the Prototype-list of the Marionette-Object i can see the method.
Any ideas what i'm missing here?

Your require.config ({ … }) should be in main.js and also as Ratweb_on indicated, there should not be “deps: [‘main’]” in the require.config.
You can follow this example in here, and ignore the jquerymobile stuffs. Essentially it dose the initialization in the same way as your code intended.
See main.js and app.js.
Updated
In your app.js
var app = Marionette.Application();
Should be
var app = new Marionette.Application();
