Cant install backpack 6 on laravel 10

[k-wiese]

When i ran composer require backpack/crud i had these composer errors:

i used composer require backpack/crud -W and it worked but I cant install devtools

Tried few laravel versions and php 8.1, 8.2, 8.3

Hey @k-wiese I am not aware of such package carbonphp/carbon-doctrine-types.

It seems one of our requirements is not compatible with the requirements of the mentioned package. It requires doctrine/dbal 4.0 while we install 3.0, AFAIK is also the version Laravel uses: https://github.com/laravel/framework/blob/484e9c2c78637e3484681d7569a0e3f878dcd594/composer.json#L98

As I understand, 4.0 still in development, at least from branch readme: https://github.com/doctrine/dbal/tree/4.0.x

You can probably work around it by setting your composer.json to accept minimum-stability: dev and trying to force doctrine/dbal: ^4.0.

Alternatively use version ^2.0 of that package: https://github.com/CarbonPHP/carbon-doctrine-types/releases/tag/2.0.0

We can only think in adding support for 4.0 when it's released as a stable version, in fact the last release RC-1 had breaking changes, so it would be careless to add core support for a work in progress. https://github.com/doctrine/dbal/releases/tag/4.0.0-RC1

Let me know how it goes.

Cheers

The other day i was facing the same issue.
I ende up adding "backpack/crud": "^6.4", to composer manually and then use composer update.
This donwngrade the version to 2.1

The key is nesbot/carbon is using "carbonphp/carbon-doctrine-types": "*", and whit the installation of laravel you install a version higher that backpack in my case installed the version 3.1
