Archlinux: pip install pgadmin4 error: Invalid version

Question

I'm trying to install pgadmin4 on Archlinux using pip inside a virtual environment pip install pgadmin4. Versions 8.11 and above (current is 8.14) fail and raise InvalidVersion exception:

ERROR: Exception:
...
pip._vendor.packaging.version.InvalidVersion: Invalid version: '6.12.4-arch1-1'

I tried downgrading setuptools to version 65, but in vain.

Version 8.10 is working fine pip install pgadmin4==8.10 (with setuptools-70.3.0 installed as a dependency) .

If I understood well, Python ecosystem recently made some version formatting guidelines mandatory and "refuses to work with" any software that do not comply with them. So Archlinux version format '6.12.4-arch1-1' should be changed to comply with those guidelines in order for pgadmin4 to be installed ... Please correct me if I'm wrong.

Any clues on how to install the latest version of pgadmin4?

PS: If this can help, here is my full stack trace:
