Your requirements could not be resolved to an installable set of packages.

Problem 1
- nekoding/tripay[v1.0.0, ..., v1.1.2, v2.0.0] require illuminate/support ^8.0 -> found illuminate/support[v8.0.0, ..., v8.83.27] but these were not loaded, likely because it conflicts with another require.
- Root composer.json requires nekoding/tripay * -> satisfiable by nekoding/tripay[v1.0.0, v1.1.0, v1.1.1, v1.1.2, v2.0.0].

You can also try re-running composer require with an explicit version constraint, e.g. "composer require nekoding/tripay:*" to figure out if any version is installable, or "composer require nekoding/tripay:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
