When I run: phpcs /path/to/module --standard=MEQP2 It gives me the following error

PHP Fatal error: Trait 'MEQP\Utils\Helper' not found in /opt/marketplace-eqp/MEQP2/Sniffs/Classes/NameResolutionSniff.php on line 23

}

and line no 23 is :

use Helper;

Any idea how to fix this issue?

I recently faced the same issue. The current magento coding standard version is not compitable with latest code sniffer version. Try to install 3.0.0 of code sniffer version it will work.
