Php Construct（）必须是实例

我正在遵循，我面临着这个错误：

“可捕获的致命错误：参数1传递到Album\Model\AlbumTable:：\uu构造（）必须是Zend\Db\TableGateway\TableGateway的实例，给定的Zend\Db\Adapter\Adapter的实例，在第33行的/var/www/CommunicationApp/module/Album/module.php中调用，在第11行的/var/www/CommunicationApp/module/Album/src/Album/Model/AlbumTable.php中定义”

我不知道我遗漏了什么，因为它与教程完全相同

<?php

namespace Album\Model;

use Zend\Db\TableGateway\TableGateway;

class AlbumTable
{
 protected $tableGateway;

 public function __construct(TableGateway $tableGateway)
 {
     $this->tableGateway = $tableGateway;
 }

 public function fetchAll()
 {
     $resultSet = $this->tableGateway->select();
     return $resultSet;
 }

 public function getAlbum($id)
 {
     $id  = (int) $id;
     $rowset = $this->tableGateway->select(array('id' => $id));
     $row = $rowset->current();
     if (!$row) {
         throw new \Exception("Could not find row $id");
     }
     return $row;
 }

 public function saveAlbum(Album $album)
 {
     $data = array(
         'artist' => $album->artist,
         'title'  => $album->title,
     );

     $id = (int) $album->id;
     if ($id == 0) {
         $this->tableGateway->insert($data);
     } else {
         if ($this->getAlbum($id)) {
             $this->tableGateway->update($data, array('id' => $id));
         } else {
             throw new \Exception('Album id does not exist');
         }
     }
 }

 public function deleteAlbum($id)
 {
     $this->tableGateway->delete(array('id' => (int) $id));
 }
 }

您应该将TableGetway传递给AlbumTable。更改Module.php并将getServiceConfig替换为：

 public function getServiceConfig()
 {
     return array(
         'factories' => array(
             'Album\Model\AlbumTable' =>  function($sm) {
                 $tableGateway = $sm->get('AlbumTableGateway');
                 $table = new AlbumTable($tableGateway);
                 return $table;
             },
             'AlbumTableGateway' => function ($sm) {
                 $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                 $resultSetPrototype = new ResultSet();
                 $resultSetPrototype->setArrayObjectPrototype(new Album());
                 return new TableGateway('album', $dbAdapter, null, $resultSetPrototype);
             },
         ),
     );
