    private $eavSetupFactory;

    public function __construct(
        \Magento\Backend\App\Action\Context $context,
        \Magento\Framework\Setup\ModuleDataSetupInterface $dataSetup,
        \Magento\Eav\Setup\EavSetupFactory $eavSetupFactory
    ) {
        $this->dataSetup = $dataSetup;
        $this->eavSetupFactory = $eavSetupFactory;
        parent::__construct($context);
    }

    public function execute() {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $this->dataSetup]);
        $eavSetup->removeAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'prod_special_descr');

        $this->messageManager->addSuccess('attribute removed');
        $this->_redirect('admin/dashboard/');
    }
}

您可以使用以下设置脚本删除属性：

<?php

namespace Namespace\Company\Setup;

use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->removeAttribute(
          \Magento\Catalog\Model\Product::ENTITY,
            'my_attribute');
    }
}
