Errore: [$ injector: unpr] Fornitore sconosciuto: $ scopeProvider <- $ scope Errore

Question

Viene visualizzato questo errore comune Errore: [$injector:unpr] Unknown provider: $scopeProvider <- $scope con il mio caso di test. So che questo è comune e ci sono pochi altri thread che spiegano con le soluzioni. Ma davvero non sono riuscito a trovare una risposta al mio problema. Qualcuno può indicarmi la giusta direzione?

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

Sostituire

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

da

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

Il regolatore deve essere iniettato con un argomento di nome $ portata, non campo di applicazione. E $ rootScope non fa parte dei collaboratori iniettati del controller.

Answer 2

stesso errore ho dovuto dimenticare di mettere '$' prima scope in

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

})
