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

  Problem 1
    - namelivia/laravel-fitbit 0.0.1 requires php ^7.0 -> your php version (8.0.27) does not satisfy that requirement.
    - namelivia/laravel-fitbit[0.0.2, ..., 0.0.5] require php ^7.1 -> your php version (8.0.27) does not satisfy that requirement.
    - namelivia/laravel-fitbit 0.0.6 requires php ^7.3 -> your php version (8.0.27) does not satisfy that requirement.
    - namelivia/laravel-fitbit 0.0.7 requires illuminate/contracts 5.5.*|5.6.*|5.7.*|5.8.*|6.*|7.*|8.* -> found illuminate/contracts[v5.5.0, ..., v5.8.36, v6.0.0, ..., v6.20.44, v7.0.0, ..., v7.30.6, v8.0.0, ..., v8.83.27] but these were not loaded, likely because it conflicts with another require.
    - Root composer.json requires namelivia/laravel-fitbit * -> satisfiable by namelivia/laravel-fitbit[0.0.1, ..., 0.0.7].

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

Can't install it on my localhost (MAC, MAMP, Php 8.0.8) and laravel... would be nice
