Erreur à l'installation de Pygame

Bonjour,
J'utilise un mac et voulant apprendre a créer des jeux sur python j'ai chercher comment installer le module "Pygame".
Cependant dès que j'entre la commande: "python -m pip install pygame" sur le terminal afin de le télécharger mais j'ai le mesage suivant qui apparaît:
"DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
Defaulting to user installation because normal site-packages is not writeable
