Grunt Karma PhantomJS - SyntaxError: Unexpected token '<'?

I keep getting an error when running this in my terminal (at the location of gruntfile.js):

grunt karma

The solutions here either didn't work or are no longer an option - http://ift.tt/2rYnrgz

Here is the output:

Here is my code:

karma.config.js

module.exports = function(config) {
    config.set({

    frameworks: ['jasmine'],


    files: [
      'bower_components/angular/angular.js',
      'bower_components/angular-mocks/angular-mocks.js',
      'app/**/*.js',
    ],

    port: 8082

    browsers: ['PhantomJS'],

    plugins: [
       'karma-phantomjs-launcher',
       'karma-jasmine',
       'karma-ng-html2js-preprocessor'
    ],

    logLevel: config.LOG_INFO,
})};

grunt test block for karma in gruntfile.js

karma: {
    unit: {
        configFile: 'karma.config.js',
        singleRun: true,
    }
}

homeCtrl.spec.js

describe('HomeCtrl', function() {
    beforeEach(module('myApp'));

    var HomeCtrl;
    beforeEach(inject(function($controller){ 
        HomeCtrl = $controller('HomeCtrl');
    }));

    describe('message', function() {
        it('should read hello', function() {
            expect(HomeCtrl.message).toBe('Hello');
        });
    });

});

homeCtrl.js

angular.module('RevisionApp')
    .controller('HomeCtrl', ($scope) => {
        $scope.message = 'hello';    
    })

Any input would be much appreciated, thanks.
