Question

I am getting below issue while upgrading to Magento version 2.4.4 on php 8

Your requirements could not be resolved to an installable set of packages.

Problem 1 - phpunit/phpunit 6.5.14 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.9 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.8 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.7 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.6 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.5 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.4 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.3 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.2 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.14 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.13 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.12 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.11 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.10 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.1 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - phpunit/phpunit 6.5.0 requires php ^7.0 -> your PHP version (8.1.4) does not satisfy that requirement. - Installation request for phpunit/phpunit ~6.5.0 -> satisfiable by phpunit/phpunit[6.5.0, 6.5.1, 6.5.10, 6.5.11, 6.5.12, 6.5.13, 6.5.14, 6.5.2, 6.5.3, 6.5.4, 6.5.5, 6.5.6, 6.5.7, 6.5.8, 6.5.9].

Do we need to upgrade the phpunit version manually?

Answer 1

you need to find the "require-dev" in your magento root composer.json file

"require-dev": {
 "allure-framework/allure-phpunit": "~1.5.0",
 "dealerdirect/phpcodesniffer-composer-installer": "^0.7.0",
 "friendsofphp/php-cs-fixer": "~3.3.0",
 "lusitanian/oauth": "~0.8.10",
 "magento/magento-coding-standard": "*",
 "magento/magento2-functional-testing-framework": "^3.7",
 "pdepend/pdepend": "~2.10.0",
 "phpmd/phpmd": "^2.9.1",
 "phpstan/phpstan": "~1.2.0",
 "phpunit/phpunit": "~9.5.0",
 "sebastian/phpcpd": "^6.0.3",
 "squizlabs/php_codesniffer": "~3.6.0",
 "symfony/finder": "^5.2"
 }

replace this code after you need just run composer update command

Answer 2

Looks like your outdated list of PHPUnit versions. I believe only PHPUnit 9+ has PHP 8 compatibility Try to clean up the composer cache by executing composer clearcache

Answer 3

You need to manually update the version of phpunit/phpunit 6.5.14 to "phpunit/phpunit": "^9" in composer.json After then run below command:

composer require magento/product-community-edition 2.4.4 --no-update

composer update
