Warning about using obsolete setup.py install

[Francesco-lodolo]

Noticed while installing lxml 4.9.1 via pip within a GitHub workflow

DEPRECATION: lxml is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

This is CRITICAL issue I assume.
Since
when trying to instal lxml pip on python '3.11',
the message occured and not working.
Howcome still not prepared for 3.11 yet?

platform : windows 11
python version : 3.11
python archtecture : 32bit

Mitchell, I think you are facing a different issue, please double check the error message that prevented you from installing whatever you were wanting to install.

The issue reported by the OP affects only pip 23.1+ (not related to Python 3.11), but the latest version released of pip so far is 22.3. If you are facing this issue because of an unreleased pip version installed, you are be able to work around the issue by using the --use-pep517 flag

And Howcome still not prepared for 3.11 yet? Well, consider contributing to this free software and implement pyproject.toml in it. The whole community will love such contribution.

- Try clean install with all official releases. It happen.
non of un official nightly build are used.
pip 22.3 installed.

- Try it on windows 11 or whatever windows with 'python 3.11-32bit'.
it happens.

- open source or free software does not mean that unprepared or unprofressional amaturistic product.
the open or free software must be more professionally prepared on time(time to marklet) than commercial.
be sharp.

Mitchell, I don't have an Windows system nor I am the maintainer, so I'm unable to help you debugging that. Good luck with that issue.
