HTTP 500 error because setup:upgrade doesn't work

Question

I created a class and I can't understand why when I pass a second parameter give a error HTTP 500.

I'm trying to do a simple code, like this:

  namespace Ahimsa\FooterLinks\Block;

  use \Magento\Framework\View\Element\Template as Template;


class FooterLinks extends Template
{
 protected $_storeManager;
 protected $categoryRepository;
 protected $_categoryHelper;

 public function __construct(\Magento\Framework\View\Element\Template\Context $context, \Magento\Catalog\Helper\Category $categoryHelper)
 {

    $this->_categoryHelper = $categoryHelper;
    parent::__construct($context);
 }
}

Anyone knows what I'm doing wrong?

Answer 1

I found the error :). I was executing magento commands inside cmd in Php Storm IDE. When I executed in Mac Terminal the command bin/magento setup:upgrade work's fine. Thank's guys.
