Answer 1

ZendSkeletonApplication已defines translator as a factory

'service_manager' => array(
    'factories' => array(
        'translator' => 'Zend\Mvc\Service\TranslatorServiceFactory',
    ),
),

同一服务不能同时定义为别名和工厂。

您链接的教程适用于较旧的ZendSkeletonApplication，它将translator定义为别名。

别名可以在配置合并时覆盖别名，因此它不会导致任何错误。

要解决此问题，请从module\Admin\config\module.config.php中删除translator别名声明
