使用sqlite内存的phinx迁移在0.9.2中似乎不起作用，我有一个非常简单的应用程序，只有一个表（产品）。运行迁移后，产品表不存在：

use Symfony\Component\Yaml\Yaml;
use Phinx\Config\Config;
use Phinx\Migration\Manager;
use Symfony\Component\Console\Input\StringInput;
use Symfony\Component\Console\Output\NullOutput;

$pdo = new PDO('sqlite::memory:', null, null, [
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
]);

$settings = Yaml::parseFile('../phinx.yml');
$settings['environments']['testing'] = [
    'adapter'       => 'sqlite',
    'connection'    => $pdo
];
$config = new Config($settings);

$manager = new Manager($config, new StringInput(' '), new NullOutput());
$manager->migrate('testing');
$manager->seed('testing');

$pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_OBJ);

// This line creates an exception of table doesn't exist
$pdo->query("SELECT * FROM product");

最后一行查询生成以下异常的产品表：
pdoexception:sqlstate[hy000]：常规错误：1第43行没有这样的表：product in/home/vagrant/code/ecommerce/public/index.php
为了完整起见，以下是与mysql开发环境完美配合的产品迁移：

use Phinx\Migration\AbstractMigration;

class Product extends AbstractMigration
{
    public function change()
    {
        $table = $this->table('product');
        $table->addColumn('name', 'string', ['limit' => 100, 'null' => false])
            ->addColumn('price', 'integer')
            ->create();
    }
}
