AngularJS错误未知提供者

angularjs

我正在尝试在html页面中显示配置的值authorversion角值服务中的版本代码,但显示的不是作者的名字,这是html代码

    <!doctype html>
<html lang="en" ng-app="myApp">
<head>
  <meta charset="utf-8">
  <title>My AngularJS App</title>
  <link rel="stylesheet" href="css/app.css"/>
</head>
<body>
  <ul class="menu">
    <li><a href="#/view1">view1</a></li>
    <li><a href="#/view2">view2</a></li>
  </ul>

  <div ng-view></div>

  <div>Angular seed app: v<span app-version></span></div>
  <div>Author is : <span app-author></span></div>


  <script src="lib/angular/angular.js"></script>
  <script src="js/app.js"></script>
  <script src="js/services.js"></script>
  <script src="js/controllers.js"></script>
  <script src="js/filters.js"></script>
  <script src="js/directives.js"></script>
</body>
</html>

这是指令…

angular.module('myApp.directives', []).
  directive('appVersion', ['version', function(version) {
    return function(scope, elm, attrs) {
      elm.text(version);
    };
  }])
  .directive('appAuthor', ['author', function(author) {
    return function(scope, elm, attrs){
        elm.text(author);
    };
  }]);

这是在其中配置authorversion值的服务部分

    angular.module('myApp.services', []).
  value('version', '0.1')
  .value('author','JIM');

我在开发人员控制台中遇到的错误是

Error: Unknown provider: authorProvider <- author <- appAuthorDirective

确保将这些模块( myApp.servicesmyApp.directives )作为主要应用程序模块的依赖项加载,如下所示:

angular.module('myApp', ['myApp.directives', 'myApp.services']);
