Testing the 3.12 package, trying to make a virtual env fails. I think this is
because it is looking for the pip wheel.
I've installed the available 3.12 packages (pip, wheel, setuptools, devel).
venv fails with/without --system-site-packages. I think venv is trying to run
'-m ensurepip' which seems to
have a dependency on pip wheel.
$ python3.12 -m venv /srv/pyvenvs/py312
Error: Command '['/srv/pyvenvs/py312/bin/python3.12', '-m', 'ensurepip',
'--upgrade', '--default-pip']' returned non-zero exit status 1.
$ python3.12 -m venv --system-site-packages /srv/pyvenvs/py312
Error: Command '['/srv/pyvenvs/py312/bin/python3.12', '-m', 'ensurepip',
'--upgrade', '--default-pip']' returned non-zero exit status 1.
Trying -m ensurepip directly yields:
$ python3.12 -m ensurepip
[...snip...]
FileNotFoundError: [Errno 2] No such file or directory:
'/usr/lib/python3.12/ensurepip/_bundled/pip-24.3.1-py3-none-any.whl'
This works with the previously working 3.9 installation. (I haven't tried the
updated 3.9 install yet.)
For 3.9 it looks like the pip*.whl file is in a different location:
$ find /usr/lib/python* -name 'pip*.whl'
/usr/lib/python3.9/site-packages/virtualenv/seed/wheels/embed/pip-20.3.4-py2.py3-none-any.whl
/usr/lib/python3.9/site-packages/virtualenv/seed/wheels/embed/pip-21.3.1-py3-none-any.whl
/usr/lib/python3.9/site-packages/virtualenv/seed/wheels/embed/pip-23.0.1-py3-none-any.whl
I haven't tried to install/build any modules/wheels since the intent was to
test the new packages.
Hopefully I'm not missing something obvious.
Thanks!

CYGWIN CHANGES
Only python 3.9 and 3.12 are updated.
Python 2, 3.6, 3.7, 3.8 are not anymore supported upstream.
https://devguide.python.org/versions/#versions
The main packages include postinstall script that
use "alternatives" to define for
/usr/bin/python
/usr/bin/python3
/usr/bin/idle3
/usr/bin/pydoc3
a default to the highest package available.
$ alternatives --display python
python - status is auto.
link currently points to /usr/bin/python3.12
/usr/bin/python3.9 - priority 39
/usr/bin/python3.12 - priority 312
Current `best' version is /usr/bin/python3.12.
Rationale:
https://www.python.org/dev/peps/pep-0394/
In other systems as Debian
/usr/bin/python is discouraged.
