控制器Angular JS的未知提供程序

Question

我对MEAN堆栈很新，并且正在尝试将新集合合并到数据库中。我将我的代码基于此示例http://jasonwatmore.com/post/2015/12/09/MEAN-Stack-User-Registration-and-Login-Example.aspx并且已经使用它的代码来登录和注册用户。

我基本上尝试做同样的事情，但是使用课程而不是用户，因此尝试复制影响课程集合的用户集合的所有文件和控制器。所有功能都适用于涉及用户的所有内容，但是当我尝试为课程执行相同操作时出现以下错误：未知提供者：CourseServiceProvider＆lt; - CourseService＆lt; - Admin.IndexController

我已经包含了我想象的所有代码，但如果需要其他任何内容，请告诉我。

我的目录如下所示

--index.controller.js
--index.html

   //Functions for all service.XX above, currently empty will 
look something like this(copied from app/app-services/user.service.js):
   // will user server.js who should call controllers/api/courses/method.

    function GetCurrent() {
        return $http.get('/api/users/current').then(handleSuccess, handleError);
