Bug report

When creating a new PHPStan extension repository or updating composer, PHP-Parser 5.x conflicts.

% ./vendor/bin/phpunit
PHPUnit 10.5.5 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.3.1
Configuration: /Users/megurine/repo/php/tadsan-phpstan-rules/phpunit.xml.dist

This issue can be prevented by conflict in composer.json.

No response

Expected output

This problem does not occur if PHP-Parser 5.x is prevented from being installed in the same package.

% composer why nikic/php-parser
zonuexe/tadsan-phpstan-rules -       conflicts nikic/php-parser (>= 5.0.0)      
phpunit/php-code-coverage    10.1.11 requires  nikic/php-parser (^4.18 || ^5.0)

Did PHPStan help you today? Did it make you happy in any way?

I noticed this problem when I created a new repository to write a PHPStan tutorial in Japanese.

This bug report is missing a link to reproduction at phpstan.org/try.

It will most likely be closed after manual review.

@ondrejmirtes
I published this extension to https://github.com/zonuexe/tadsan-phpstan-rules.
It works fine on master, but I can see the error on PR's branch.

This commit avoids the problem: phpstan/phpstan-src@9dac90d
