Hmm... that's odd. I just installed Backpack on a fresh Laravel project and it worked fine. @MikePageDev what does your composer.json look like?

MikePageDev commented 3 years ago

I have fixed this by removing doctrine/dbal and installing

nihadatakishiyev commented 3 years ago

I experienced similar conflict problem when trying to install doctrine/dbal to my Laravel 8 project in which backpack is already installed. Any idea why would that happen? @tabacitu

error

I also attach a copy of my composer.json file. Thanks in advance!

Deleting composer.lock solved the first problem, however problem 2 still persists.

Hi guys,

Indeed, Laravel 8 supports PHP 8, but it also supports both DBAL v2.5+ and DBAL v3.x. Backpack does support PHP 8 in the latest version, but it does not yet support DBAL v3 (see https://github.com/Laravel-Backpack/CRUD/pull/3517). We do plan to add DBAL v3 support but it could take a few days - and depending on what we find it's possible that it'll be a breaking change.

If you don't have a reason to explicitly ask for DBAL v3 (you don't use DBAL v3 features in your code), I recommend you remove the doctrine/dbal composer dependency in your project and run composer update - that should have the same result as @lotarbo and @MikePageDev 's solution. Doctrine/dbal v2.12.x does support PHP 8, so it should work just fine.

If you have a dependency that needs DBAL v3, however, since Backpack doesn't yet support DBAL v3... that's where you have a problem. The only thing to do in that case is to wait from upgrading that dependency, until we manage to add DBAL v3 support in Backpack. Hopefully we'll be able to do so in a non-breaking manner 🤞

Cheers!
