遵循Sylius定制工廠指南示例時出錯

Question

我只是在遵循自定義指南，並且在ProductFactoryInterface（ http://docs.sylius.org/en/1.0/customization/factory.html ）的自定義示例中遇到了問題

我總是得到相同的錯誤：

編譯錯誤：AppBundle \\ Factory \\ ProductFactory :: createWithVariant（）的聲明：Sylius \\ Component \\ Core \\ Model \\ ProductInterface必須與Sylius \\ Component \\ Product \\ Factory \\ ProductFactoryInterface :: createWithVariant（）：Sylius \\ Component \\ Product \\型號\\產品接口

我究竟做錯了什么？ 這是我的代碼：

namespace AppBundle\Factory;

use Sylius\Component\Core\Model\ProductInterface;
use Sylius\Component\Product\Factory\ProductFactoryInterface;

class ProductFactory implements ProductFactoryInterface
{
    /**
     * @var ProductFactoryInterface
     */
    private $decoratedFactory;

    /**
     * @param ProductFactoryInterface $factory
     */
    public function __construct(ProductFactoryInterface $factory)
    {
        $this->decoratedFactory = $factory;
    }

    /**
     * {@inheritdoc}
     */
    public function createNew(): ProductInterface
    {
        return $this->decoratedFactory->createNew();
    }

    /**
     * {@inheritdoc}
     */
    public function createWithVariant(): ProductInterface
    {
        return $this->decoratedFactory->createWithVariant();
    }

    /**
     * @return ProductInterface
     */
    public function createDisabled(): ProductInterface
    {
        /** @var ProductInterface $product */
        $product = $this->decoratedFactory->createNew();

        $product->setEnabled(false);

        return $product;
    }
}

如果您首先更改此use語句：

use Sylius\Component\Core\Model\ProductInterface;

帶有：

use Sylius\Component\Product\Model\ProductInterface;

在1.0.0版本之前，某些接口已更改，似乎並非所有文檔都相應地反映了此更改。
