Angularjs does not recognize it ipad

When I run my application on iPad, I get this error

Error[$injector:modulerr]http://errors.angularjs.org/1.5.8/$injector/modulerr?p0=ng&p1=’undefined%20is%20not%20an%20object

my angularjs application is:

var app = angular.module('nexionfiPortal', [
    'ngAnimate',
    'ngRoute', 
])

.config(function ($routeProvider) {
    $routeProvider
    .when('/', {
        templateUrl: 'views/main.html',
        controller: 'MainCtrl',
        controllerAs: 'main'
    })

.when('/email', {
    templateUrl: 'views/email.html',
    controller: 'EmailCtrl',
    controllerAs: 'email'
})

.when('/usuario/premios/:id', {
    templateUrl: 'views/premios.html',
    controller: 'PremiosCtrl',
    controllerAs: 'premios'
})
