Description

When trying to run Laravel with the Symfony 7.4 beta, see also https://github.com/symfony/symfony/releases/tag/v7.4.0-BETA1, issues arise.

Steps To Reproduce

• See https://github.com/jnoordsij/laravel-laravel/tree/symfony7.4
• Run composer install, result is:

Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Nothing to install, update or remove
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover --ansi

I ran into this issue as well.
I pinned symfony/console to version 7.3, and the problem went away.
There was a discussion about this here: #56098 (comment)

Thanks for the additional reference. The main issue here is that Laravel by default will allow 7.4 when it is stable, which currently would result in broken setups. Therefore this issue is mainly meant as a heads-up that probably some action is required before the stable 7.4 release to prevent a potentially very large sets of users of running into troubles.
