错误：[$injector:unpr] 未知提供者：$scopeProvider <- $scope 错误

Question

我收到这个常见错误 Error: [$injector:unpr] Unknown provider: $scopeProvider <- $scope with my test case 。我知道这是一个常见的问题，并且很少有其他线程解释解决方案。但我真的想不出我的问题的答案。谁能指出我正确的方向？

ViewMeetingCtrl ，

(function () {
    'use strict';
    angular.module('MyApp').controller('ViewMeetingCtrl', ViewMeetingCtrl);

    ViewMeetingCtrl.$inject = ['$scope', '$state', '$http', '$translate', 'notificationService', 'meetingService', '$modal', 'meeting', 'attachmentService'];

    function ViewMeetingCtrl($scope, $state, $http, $translate, notificationService, meetingService, $modal, meeting, attachmentService) {
        $scope.meeting = meeting;
        $scope.test = "testvalue";
        if (meeting.Status == 'Cancelled')
        {
            $scope.actionButtons = false;
        }
        else
        {
            $scope.actionButtons = true;
        }

        //more code
    }
})();

MeetingCtrlSpec.js

describe('ViewMeetingCtrl', function () {
    var $rootScope, scope, $controller, meetingService;

    beforeEach(angular.mock.module('MyApp'));

    beforeEach(inject(function ($rootScope, $controller, meetingService) {
        scope = $rootScope.$new();
        $controller('ViewMeetingCtrl', {
            meetingService: meetingService,
            '$rootScope' : $rootScope,
            scope: scope
        });       

    }));

    it('should change greeting value if name value is changed', function () {
        //some assertion
    });
});

Answer 1

替换

    $controller('ViewMeetingCtrl', {
        meetingService: meetingService,
        '$rootScope' : $rootScope,
        scope: scope
    }); 

通过

    $controller('ViewMeetingCtrl', {
        meetingService: meetingService,
        $scope: scope
    });

控制器必须注入一个名为 $scope 的参数，而不是作用域。并且 $rootScope 不是您控制器的注入协作者的一部分。

Answer 2

同样的错误我忘记在scope 之前输入'$'

app.controller("loginCtrl", function(**$**scope){

})
