Error: Argument is not a function, got undefined

FIRST. check if you have correct controller in the route definitions, same as the controller names that you are defining

communityMod.config(['$routeProvider',
  function($routeProvider) {
    $routeProvider.
      when('/members', {
        templateUrl: 'modules/community/views/members.html',
        controller: 'CommunityMembersCtrl'
      }).
      otherwise({
        redirectTo: '/members'
      });
  }]);

communityMod.controller('CommunityMembersCtrl', ['$scope',
    function ($scope) {
        $scope.name = 'Hello community';
    }]);

different controller names in this example will lead to errors, but this example is correct

SECOND check if you have imported your javascript file:

<script src="modules/community/controllers/CommunityMembersCtrl.js"></script>

Remove the [] from the name ([myApp]) of module

angular.module('myApp', [])

And add ng-app="myApp" to the html and it should work.
