when I try
composer require sonata-project/admin-bundle it doesn’t work.
Installation request for sonata-project/admin-bundle ^3.59 -> satisfiable by sonata-project/admin-bundle[3.59.0].
sonata-project/admin-bundle 3.59.0 requires symfony/asset ^4.3 -> no matching package found.
- A typo in the package name.
The package is not available in a stable-enough version according to your minimum-stability setting see https://getcomposer.org/doc/04-schema.md#minimum-stability for more details.
It’s a private package and you forgot to add a custom repository to find it.
Read https://getcomposer.org/doc/articles/troubleshooting.md for further common problems.
