Error Installing Instapy on MacOS

(Brand new to coding so this is like a foreign language to me so excuse me if this is a simple fix)
Im watching the video tutorials and I am having trouble installing.
I am:
-Using MacOS Mojave 10.141.
-Downloaded Python 3.9.1

When i run the MacOS Install.command it shows me the messages below. Please let me know if there is something I've missed or doing wrong.
Thank you!!!

Comienza leyendo MacOS Install.command y rastreando su invocación de pip, especialmente el punto de entrada /usr/local/bin/pip que aparece en el traceback. Reproduce la instalación en macOS Mojave con Python 3.9.1; el trabajo estará terminado cuando el script instale InstaPy sin el error de sintaxis reportado.
