Repositories code generation... 1/9 [===>------------------------] 11% < 1 sec 125.0 MiBPHP Fatal error: Cannot declare class Amasty\AdminActionsLog\lib\HtmlNode, because the name is already in use in /var/www/html/mydomain.com/app/code/Amasty/AdminActionsLog/lib/HtmlNode.php on line 6, note : line 6 content is "class HtmlNode {" below are 3 files of php partial source code among Amasty: (1) app\code\Amasty\AdminActionsLog\lib\HtmlNode.php

my question is : why "sudo php bin/magento setup:di:compile" ran well in php7.4 but got errors in php8.2 and how to fix it ?

thank you in advance.

Answer 1

You have upgraded to the latest Magento, which is in beta. Amasty packages do not have support for this version. There is a change from PHP to a newer version, a lot of things may be outdated, some of the objects in Magento also get updates and it is required that you update the Amasty packages to a version that is compatible firstly with PHP8.2 and secondly with Magento in a newer version.

There is not much point in fixing this. I would ask the question in the other direction. Why do you want Magento in beta instead of choosing a stable version to which 3rd party packages may have already been updated?
