Answer 1

ZendSkeletonApplication已經defines translator as a factory：

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

相同的服務不能被定義爲一個別名和作爲工廠在同一時間。

您鏈接的教程適用於較老的ZendSkeletonApplication，它將轉換器定義爲別名。
別名可以覆蓋配置合併上的別名，因此它不會導致任何錯誤。

要解決該問題，請從module\Admin\config\module.config.php刪除translator別名聲明
