[Python] Wheels created by "pip freeze" and "pip wheel" not usable with --no-index and...

I created wheels from an existing venv, that resulted in, among others, the following wheel. The wheel was created within docker, with a Python version of 3.9 (the smallest possible versions were chosen to provide maximal compatibility)

wheels/codechecker-6.23.1-cp39-cp39-linux_x86_64.whl


My requirements.txt has that version "6.23.1" listed. But when I try to install that version (with Python 3.11), using

python3 -m pip install --no-index --find-links wheels -r requirements.txt


Python gives an error message:

Looking in links: wheels
Processing wheels/alembic-1.5.5-py2.py3-none-any.whl
ERROR: Could not find a version that satisfies the requirement codechecker==6.23.1 (from > versions: none)
ERROR: No matching distribution found for codechecker==6.23.1​

My suspicion is that the version encoding of "cp39" (for CPython3.9) somehow gets in the way with using it with CPython3.11, but from what I read, wheels should be upward-compatible and Pip should be downward compatible with older wheel versions. So what could be wrong here? Both systems are 64bit systems.
