I'm facing the same issue. My PHPStorm version is: 2022.1

For somehow $installedPath ../../phpcompatibility/php-compatibility was missing during inspecting code on PHPStorm but it doesn't while using cli

it's not permanent fixing, but you may apply this patch @tuyennn @Vinai https://gist.github.com/fiko/bdec71978b458cc527df03d26a695b6c

I'm facing the same issue. Any news on this?

Any update on this? PHPCS is an important part of our workflow.

To include Magento Coding Standard as part of PHPStorm inspections, follow the steps:

• Open PHPStorm preferences
• Navigate to "Editor" | "Inspections"
• Select "PHP" | "Quality Tools" | "PHP_CodeSniffer validation"
• Set "Coding standard" to "Custom" and select path to <project_root>/vendor/magento/magento-coding-standard/Magento2/ruleset.xml
• Check "Installed standards path" and select path to <project_root>/vendor/php-compatibility/PHPCompatibility

PR adding these instructions to the documentation: AdobeDocs/commerce-php#48

I'm seeing this issue when running on CLI too

Did anyone find a proper fix for this? For us, it is only happening in our pipepline, but not locally. https://gist.github.com/fiko/bdec71978b458cc527df03d26a695b6c is rather hacky.

@sprankhub I fixed this locally by un-setting the 'installed_paths' option within PHPStorm, and relying instead on the installer plug-in. Are you perhaps running your pipeline as root? If so, you'll need to (either switch to a non-root user or) tell Composer that you really want to run plug-ins with https://getcomposer.org/doc/03-cli.md#composer-allow-superuser

@fredden thanks, buddy! Using COMPOSER_ALLOW_SUPERUSER indeed fixed it 🎉

I ran into this issue on 2.4.6-p3 and had to modify the composer script bit

"scripts": {
    "post-install-cmd": [
      "([ $COMPOSER_DEV_MODE -eq 0 ] || vendor/bin/phpcs --config-set installed_paths ../../magento/magento-coding-standard/,../../magento/php-compatibility-fork)"
    ],
    "post-update-cmd": [
      "([ $COMPOSER_DEV_MODE -eq 0 ] || vendor/bin/phpcs --config-set installed_paths ../../magento/magento-coding-standard/,../../magento/php-compatibility-fork)"
    ]
}

I don't know at what point the paths changed from phpcompatibility/php-compatibility to magento/php-compatibility-fork but inspections now work on my PHPStorm
