PHP 8.0.0 Installation failed

[racile]

I did a fresh install of symfony using PHP 7.4.13 then the symfony/orm-pack without a problem, I replicated the same using PHP 8.0.0 but encountered an error:

# composer require symfony/orm-pack
Using version ^2.0 for symfony/orm-pack

That's because Doctrine is not yet compatible with PHP 8.

[leon-zadravec]

Since doctrine got an update for PHP 8 support (https://github.com/doctrine/orm/releases/tag/2.8.0) is it possible to update this package too?

[nicolas-grekas]

This package is already compatible with php8. Btw, you should unpack it!

[leon-zadravec]

When I'm calling composer require symfony/orm-pack I still get the same error as racile here

[nicolas-grekas]

Sure you do, because of doctrine/doctrine-migrations-bundle which is not yet compatible with php8.
