我在我的测试用例中遇到了这个常见的错误 Error: [$injector:unpr] Unknown provider: $scopeProvider <- $scope。我知道这是一个常见的问题，并且有几个其他的线程解释了解决方案。但我真的想不出如何解决我的问题。有谁能指导我正确的方向吗？

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
    });
});

打错了！应该是 $scope: scope，你少了一个美元符号，并且不需要注入 $rootScope，因为你并不依赖它，尽管这不是问题的关键。 - PSL

@PSL，非常感谢您的回复。这解决了我的问题，但最终导致了另一个问题。它显示“错误：[$injector：unpr]未知提供程序：meetingProvider <- meeting <- ViewMeetingCtrl”。您能否为此错误提供一些帮助？因为我在我的解决方案中没有任何名为meetingProvider的东西。 - Malik

我犯了同样的错误，忘记在scope前面加上'$'

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

})

替换

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

by

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

控制器必须注入一个名为 $scope 的参数，而不是 scope。$rootScope 不是您控制器注入的合作者之一。
