Adding an attribute programmatically in Magento 2.1

Question

I am creating a product attribute for sorting which will be int type : where I am getting following error:

PHP Fatal error: Uncaught Error: Class 'Magento\Catalog\Model\Resource\Eav\Attribute' not found in /opt/bitnami/apps/magento/htdocs/app/code
/Vendor/Module/Setup/InstallData.php:57

Here is my Vendor/Module/Setup/InstallData.php

<?php

namespace Vendor\Module\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;

    /**
     * Init
     *
     * @param EavSetupFactory $eavSetupFactory
     */
    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    /**

     */
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        /** @var EavSetup $eavSetup */
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

        /**
         * Add attributes to the eav/attribute
         */

        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'sorting_attribute',
            [
                'type' => 'int',
                'backend' => '',

Change the code in module.xml file to this.

    <?xml version="1.0" encoding="UTF-8"?>
<config  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="Vendor_Module"  setup_version="1.0.0">
     <sequence>
            <module name="Magento_Catalog"/>
        </sequence>
    </module>
</config>

Replace your code with this code in InstallData.php.

namespace Vendor\Module\Setup;

use Magento\Catalog\Model\Product;
use Magento\Catalog\Model\Product\Type;
use Magento\Catalog\Model\Resource\Eav\Attribute;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;


/**
 * @codeCoverageIgnore
 */
class InstallData implements InstallDataInterface
{
    /**
     * EAV setup factory
     *
     * @var EavSetupFactory
     */
    private $eavSetupFactory;
    /**
     * Init
     *
     * @param EavSetupFactory $eavSetupFactory
     */
    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
        /* assign object to class global variable for use in other class methods */
    }

    /**
     * {@inheritdoc}
     * @SuppressWarnings(PHPMD.ExcessiveMethodLength)
     */
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
         $setup->startSetup();
        /** @var EavSetup $eavSetup */
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);


        /**
         * Add attributes to the eav/attribute
       */
       $eavSetup->addAttribute(
         \Magento\Catalog\Model\Product::ENTITY,
       'sorting_attribute',
       [
       'type' => 'int',
        'backend' => '',
        'frontend' => '',
        'label' => 'Sorting Attribute',
        'input' => 'text',
        'class' => '',
        'source' => '',
        'global' => 1,
        'visible' => true,
        'required' => false,
        'user_defined' => true,
        'default' => 0,
        'searchable' => false,
        'filterable' => false,
        'comparable' => false,
        'visible_on_front' => true,
        'used_in_product_listing' => true,
        'unique' => false,
        'apply_to' => 'simple,configurable,virtual,bundle,downloadable,grouped',
        'group'=> 'General'
       ]
      );






       $setup->endSetup();
    }
}

Change: \Magento\Catalog\Model\Resource\Eav\Attribute::SCOPE_GLOBAL to \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL.

     //'global' => \Magento\Catalog\Model\Resource\Eav\Attribute::SCOPE_GLOBAL, <= Remove this line
     'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
