Upgrading to Laravel 9, the version 8.1 does not work anymore
Your requirements could not be resolved to an installable set of packages.
Problem 1
- arcanedev/support 8.0.0 requires laravel/framework ^8.0 -> found laravel/framework[v8.0.0, ..., 8.x-dev] but it conflicts with your root composer.json require (^9.0).
- arcanedev/support 8.0.1 requires php ^7.3 -> your php version (8.1.1) does not satisfy that requirement.
- illuminate/contracts[v8.0.0, ..., v8.11.2] require php ^7.3 -> your php version (8.1.1) does not satisfy that requirement.
- Only one of these can be installed: illuminate/contracts[dev-master, v5.0.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev], laravel/framework[v9.0.0-beta.1, ..., 9.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it.
- arcanedev/support 8.1.0 requires illuminate/contracts ^8.0 -> satisfiable by illuminate/contracts[v8.0.0, ..., 8.x-dev].
- arcanedev/laravel-notes 8.1.0 requires arcanedev/support ^8.0 -> satisfiable by arcanedev/support[8.0.0, 8.0.1, 8.1.0].
- Root composer.json requires arcanedev/laravel-notes ^8.1 -> satisfiable by arcanedev/laravel-notes[8.1.0].
- Root composer.json requires laravel/framework ^9.0 -> satisfiable by laravel/framework[v9.0.0-beta.1, ..., 9.x-dev].
