I am unable to get the following to work, I keep getting an Unknown provider error. Any ideas?

var app = angular.module('app', ['ui.router']);

app.config(function($stateProvider, $urlRouterProvider) {

    $urlRouterProvider.otherwise("/");

    $stateProvider
        .state("home", {
            url : "/",
            templateUrl : "resources/static/views/home.html",
            controller: "HomeCtrl",
            controllerAs: "homeCtrl"
        }
    );
});

app.controller("HomeCtrl", ["$scope", function ($scope) {

    var _this = this;

    // do stuff

}]);

Full Error:

angular.1.5.8.min.js:118 Error: [$injector:unpr] http://errors.angularjs.org/1.5.8/$injector/unpr?p0=<div ui-view="" class="ng-scope">copeProvider%20%3C-%20%24scope%20%3C-%20HomeCtrl

And link

And html

<div>Home</div>

For clarity, I need to use controllerAs, so removing it is not an option.

EDIT: Must be a bug in version 0.3.1 of ui.router, when I switched to 0.3.2 it worked fine.

You are missing data-ui-view in index.html,

<body data-ng-app="myApp">
  <h2>AngularJS Ui router - Demonstration</h2>
  <div data-ui-view=""></div>
</body>

Controller:

var myApp = angular.module("myApp", ['ui.router']);
myApp.config(function($stateProvider, $urlRouterProvider) {
  $urlRouterProvider.when("", "/home");
  $stateProvider
    .state("home", {
      url: "/home",
      templateUrl: "home.html",
      controller: 'HomeCtrl',
      controllerAs: "home"
    });
});
myApp.controller('HomeCtrl', ['$scope', function($scope) {
    var vm = this;
     vm.hello = "DEMO";

}]);
