Problem with PHP version 8.3 about php-cs-fixer HOT 3 CLOSED

Support for PHP 8.3 was officially added in v3.40.0, so you need to upgrade Fixer in your project to this version. Alternatively you can set PHP_CS_FIXER_IGNORE_ENV=1 when running Fixer to allow higher version of PHP. But using latest version of the tool is highly recommended 🙂.

from php-cs-fixer.

So by your Packagist config, Im using latest Packagist version.

What is "your Packagist config"? This one: https://packagist.org/packages/friendsofphp/php-cs-fixer, showing that latest version is v3.41.1?

kub@:~/code$ mkdir issue7596
kub@:~/code$ cd issue7596
kub@:~/code/issue7596$ composer require --dev --quiet friendsofphp/php-cs-fixer
kub@:~/code/issue7596$ composer show | grep fixer
friendsofphp/php-cs-fixer          v3.41.1 A tool to automatically fix PHP code style

☝🏼 shows it is fine.

My first guess is that PHP version (maybe set via platform) is stopping you from installing newer version, see: compare/v3.4.0...v3.5.0 - 3.4.0 supports PHP >= 7.2.5, when next one, 3.5.0 requires minimum PHP 7.4.

A second guess would be that other dependencies are blocking you from upgrading PHP CS Fixer, try:

composer why-not friendsofphp/php-cs-fixer ^3.40

I think the problem is Packagist version config...

I used composer require friendsofphp/php-cs-fixer to install PHPCSFixer. So by your Packagist config, Im using latest Packagist version.

Here is my composer.json file:

    "require": {
        "friendsofphp/php-cs-fixer": "^3.4"
    },

See? version "^3.4" will be installed by default.
