AngularJS - getting "Uncaught Error: [$injector:modulerr]" message on a simple app

我跟随Linkster的在线教程，展示了如何使用MEAN堆栈制作reddit克隆。(https://thinkster.io/mean-stack-tutorial angular-routing)

我已经尝试了所有的方法，但似乎都没有效果。知道怎么回事吗?任何帮助/想法都很感激:)

                <span ng-hide="post.link">
                    {{post.title}}

——app.js ----------------

var app = angular.module('flapperNews', ['ui-router']);
app.config([
'$stateProvider',
'$urlRouterProvider',
  function($stateProvider, $urlRouterProvider){
$stateProvider
  .state ('home', {
    url: "/home",
    templateUrl: "/home.html",
    controller: 'MainCtrl'
  });
  // .state('posts', {
  //   url: '/posts/{id}',
  //   templateUrl: '/posts.html',
  //   controller: 'PostsCtrl'
  // }); 
  $urlRouterProvider.otherwise('home');
  }])
app.factory('posts', [function(){
  var o = {
    posts: [{title: 'hello post1', link: '', upvotes: 0 }]
  };
  return o;
}])
app.controller('MainCtrl', [
'$scope',
'posts',
function($scope, posts){
  $scope.test = 'Hello world!';
  $scope.posts = posts.posts;
 $scope.addPost = function(){
        if(!$scope.title || $scope.title === '') { return; }
        $scope.posts.push({
      title: $scope.title,
      link: $scope.link,
      upvotes: 0});
    $scope.title = '';
    $scope.link = '';
  }
  $scope.incrementUpvotes = function(post) {
     post.upvotes += 1;
  }
}]);

用var app = angular.module('flapperNews', ['ui.router']);代替var app = angular.module('flapperNews', ['ui-router']);
