I am using Laravel 11.8.0 for my web application project and wanted to make an admin page. Therefore, I tried to install laravel-admin. However, it gave me an error saying, "Your requirements could not be resolved to an installable set of packages." Does this mean that laravel-admin is not compatible with laravel 11? I was confused because laravel-admin on GitHub just states that the requirements are PHP >= 7.0.0 and Laravel >= 5.5.0.
Below is the full error message:
astroid@Tatsunoris-MacBook-Pro wvs % composer require encore/laravel-admin
./composer.json has been updated
Running composer update encore/laravel-admin

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require encore/laravel-admin:*" to figure out if any version is installable, or "composer require encore/laravel-admin:^2.1" if you know which you need.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
When I searched up, the versions supported by the encore/laravel-admin package, is Laravel versions up to 8.x. However, this contradicts to what it says on the GitHub page of laravel-admin, stating Laravel >= 5.5.0. is the minimum requirement.
That package was updated one than a year ago. I recommend that you don't use unmaintained libraries on your project.
For what I see, the latest version of that package need a version of doctrine/dbal that is not compatible with Laravel 11.
I also see that this admin library has some commits that haven't been tagged, so maybe you can try to install it using composer require encore/laravel-admin:dev-master
