我读过&试过这些:ZF2 - get 无法获取或为 getAlbumTable 创建一个实例

i read & tried these : ZF2 - get was unable to fetch or create an instance for getAlbumTable

总是不清晰

推荐答案

这是因为 DB 配置错误，要解决这个问题，您必须在 main config 文件夹中的 global.php 中配置 DB.代码如下，复制粘贴和只需更改数据库名称和密码，

This is because of DB configuration error, to solve this you have to configure DB in global.php in main config folder.Code is given below, Copy paste and Just change the db name and password,

return array(
    'db' => array(
        'driver'         => 'Pdo',
        'dsn'            => 'mysql:dbname=zf2tutorial;host=localhost',
        'driver_options' => array(
            PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
        ),
        'username'       => 'root',
        'password'       => ''
    ),
    'service_manager' => array(
        'factories' => array(
            'Zend\Db\Adapter\Adapter'
                    => 'Zend\Db\Adapter\AdapterServiceFactory',
        ),
    ),
);
