Problem 1
- Root composer.json requires anlutro/l4-settings ^1.0 -> satisfiable by anlutro/l4-settings[v1.0.0].
- anlutro/l4-settings v1.0.0 requires illuminate/support >=4.2 <9.0 -> found illuminate/support[v4.2.0-BETA1, ..., 4.2.x-dev, 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] but these were not loaded, likely because it conflicts with another require.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require anlutro/l4-settings:*" to figure out if any version is installable, or "composer require anlutro/l4-settings:^2.1" if you know which you need.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
