I am trying to update my Magento to 2.4.7-p5 and I am getting this error during the update process after running composer update:
Cannot declare class Dealerdirect\Composer\Plugin\Installers\PHPCodeSniffer\Plugin, because the name is already in use in vendor/dealerdirect/phpcodesniffer-composer-installer/src/Plugin.php on line 35
Using composer 2.2 ... what could be the reason and how can I solve this?
Thanks
You probably try to install in the vendor the class while the class exist in your app/code, or the opposite, trying to add it in app/code while it already exist in your vendor. Check if the class namespace does not already exist in your code base.
Also to update a Magento store there is a better approach to my point of view rather than relying on composer update. Why's that ? Cause when a new user will try to install the project he will always run composer install in the first place.
Supposing we are in local first
Step 1 : Delete vendor folder.
Step 2 : Delete composer.lock
Step 3 : COMPOSER_MEMORY_LIMIT=-1 composer require-commerce magento/product-community-edition:2.4.7-p5 -W
Step 4 : Set up & di compile to make sure everything is fine.
