Restangular: Error: Unknown provider: RestangularProvider <- Restangular

Question

I'm trying to use restangular as an adapter for rails rest api, but i can't make it work properly. I've downloaded the latest version and put the file in vendor/assets/javascripts folder. But once i try to load the app i get the following error:

Error: Unknown provider: RestangularProvider <- Restangular

Here is my application.js file

//= require jquery
//= require bootstrap
//= require suggest.min
//= require angular
//= require underscore
//= require restangular
//= require angular-strap.min
//= require angular-cookies
//= require angular-resource
//= require angular/index

The app is initialized as follows:

angular.module('angularApp', [
  'ngCookies', 
  'restangular'
]);
angular.module('angularApp.services', [
  'ngResource',
  'sessionService',
  'courseService'
]);
angular.module('angularApp.resources', [
  'ngResource'
]);
angular.module('angularApp.directives', []);
angular.module('angularApp.filters', []);
angular.module('angularApp.controllers', []);

var App = angular.module('angularApp', [
  'angularApp.resources',
  'angularApp.services',
  'angularApp.directives',
  'angularApp.filters',
  'angularApp.controllers',
  '$strap.directives'
  ]);

There is also a controller which tempts to use restangular without any success

angular.module('angularApp.controllers').controller('CourseListCtrl', [
  '$scope', '$location', 'Restangular', 
  function($scope, $location, Restangular) {"use strict";
    $scope.courses = Restangular.all('courses')
}]);

What am i doing wrong? It seems i've done everything described in the restangular guide, but still don't understand the reason why it's not working.

As per my comment, you're defining the module twice, the second time it overrides your restangular inclusion.
