Description

The issue #9613 is marked as completed, but using the latest version of Python, and the latest version of pip, it seems like the issue is still present.

Expected behavior

No response

pip version

24.0

Python version

3.12.3

OS

Mac OS

How to Reproduce

Let's use tqdm for this test, as it is a popular pure python package.
Currently, the latest version on pypi is tqdm 4.66.4

For each test, start with a new Python env and try to run the following:
pip install tqdm~=4.65 tqdm~=4.65.0 - Fails

pip install tqdm~=4.66 tqdm~=4.66.0 - OK
pip install tqdm~=4.66 - OK
pip install tqdm~=4.66.0 - OK
pip install tqdm~=4.65 - OK
pip install tqdm~=4.65.0 - OK

Output

Code of Conduct

Pip hasn't had a final release since #9613 was marked as completed.

You can either test this on pip main, the beta (24.1b1), or wait for pip 24.1 to release (should be very soon, once CI issues are fixed).
