I'm seeing reproducible (for me) hangs with the test Python 3.12 packages under
Cygwin 3.5.4.
First, I see a hang doing `python312 -m pip install ipython` in a venv.
ipython is a too large package with too many dependencies.
Not a good test case.
I will build some more 3.12 modules for that scoepe
I agree IPython is a complex package with a lot of dependencies, though the
hang with IPython doesn't take much to reproduce.
So yes, lets focus on the simpler problems.
The hang occurs during downloading. If the package is already downloaded
it doesn't hang. So I'm doing a `pip cache purge` to get it to reoccur.
It usually hangs on downloading Jedi which is a large-ish module.
Downloading jedi-0.19.2-py2.py3-none-any.whl (1.6 MB)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 0.0/1.6 MB ? eta -:--:--
1.6 Mb does not seem a large load
No it doesn't. But I see hangs on both Jedi and Pygments during IPython install.
If I install them individually there is no hang.
Steps I'm taking are:
# clean up from previous runs
rm -rf /srv/pyvenvs/py312
pip3 cache purge
# Create a venv in an empty directory
python3.12 -m venv --system-site-packages --without-pip /srv/pyvenvs/py312
(The --without-pip is needed because it fails without it running `-m ensurepip`
It is looking for the pip wheel but not finding it.)
$ python3.9 -m ensurepip --version
pip 19.2.3
$ python3.12 -m ensurepip --version
pip 24.3.1
$ python3.12 -m pip --version
pip 24.3.1 from /usr/lib/python3.12/site-packages/pip (python 3.12)
what is coming from your system ?
Looks like my versions appear to match yours.
Note I haven't installed the newer (test) 3.9 packages, cygcheck shows:
python39 3.9.16-1 OK
python39-pip 24.0-1 OK
$ python3.9 -m ensurepip --version
pip 19.2.3
$ python3.12 -m ensurepip --version
pip 24.3.1
$ python3.12 -m pip --version
pip 24.3.1 from /usr/lib/python3.12/site-packages/pip (python 3.12)
Also, the error I see with venv is that something you see as well or is it just
me?
$ python3.12 -m venv /srv/pyvenvs/test312
Error: Command '['/srv/pyvenvs/test312/bin/python3.12', '-m', 'ensurepip',
