Thanks Michael that worked to create the venv. Did you have any success with pip installs?
For me, simple modules like requests worked but for larger things like ipython, Python 3.12 hung hard downloading requirements. Downloading pygments-2.18.0-py3-none-any.whl (1.2 MB) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 0.0/1.2 MB ? eta -:--:--(py312) I couldn't kill python3.12 with any signal using Cygwin kill. However, I was able to end process with Windows Task Manager. Trying again and doing an strace, it seemed to get stuck in a loop on this: --- Process 29448 (pid: 4552), exception c0000005 at 0000000000000000 It is using 100% of 1 core while doing that. I could be wrong, but it looks like there might still be a hanging problem with 3.12 on Cygwin. On 1/2/2025 12:42 PM, Michael Cook wrote:
As a workaround, you can try passing `--without-pip`. I had success with this: python -m venv --system-site-packages --without-pip _venv Michael On Thu, Jan 2, 2025 at 11:38 AM Robert Terzi via Cygwin <cygwin@cygwin.com> wrote: 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!
