Javascript 角度js路由错误

我正在尝试创建一个导航菜单。。。。。这就是我的html的样子

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
    <script src="~/Scripts/Course/Course-Module.js"></script>
}
<div class="container">
    <div class="row">
        hello{{2+2}}
        <div class="navbar navbar-default">
            <div class="navbar-header">
                <ul class="nav navbar-nav">
                    <li><span class="navbar-brand">Registration</span></li>
                </ul>
            </div>
            <div class="navbar-collapse collapse">
                <ul class="nav navbar-nav">
                    <li><a href="#/Courses">Courses</a></li>
                    <li><a href="#/Instructors">Instructors</a></li>
                </ul>
            </div>

        </div>

    </div>
    <div ng-view></div>
</div>

这是因为没有在任何地方定义控制器。我还想指出，AngularJS在指出错误描述方面确实很有用。错误代码的第一行实际上链接到AngularJS站点，该站点提供了您收到的错误的基本描述。

var registrationModule = angular.module("registrationModule", ['ngRoute']);

registrationModule.config(['$routeProvider',
    function ($routeProvider) {
        $routeProvider.
            when('/Courses', {
                templateUrl: '/Templates/Courses.html',
                controller: 'CoursesController'
            }).
            when('/Instructor', {
                templateUrl: '/Templates/Instructors.html',
                controller: 'InstructorsController'
            }).
            otherwise({
                redirectTo: '/Courses'
            });
    }]);
