pip3 install --user pymedphys
Or
pip3 install --user pymedphys[user]
This was the solution for Big Sur installation for a MacOS user without administrative account.
I would go as far as to say that potentially pymedphys should always be installed without admin privileges whether one has the account access or not, either within a virtual environment, or if one must directly use the system installed Python without venv usage (which I would advise against) then to always install with the --user flag.
But that would be conventions I have inherited from Linux thinking… Potentially it is common place to polute the administrative Python namespace on MacOS
