Using cygcheck I ascertained that pip is not installed by setup.exe. Ok. I can do that. ... I did that now. Using cygcheck I now see this report: Installed package: ------------------ Name : python3-pip Version : 26.0.1 Release : 1 Architecture: noarch Size : 116 (116 B) Categories : Python Virtual Source : python-pip-26.0.1-1-src.tar.xz Summary : Python package installation tool Description : The python3-pip virtual package. Selecting this package for installation will cause the python39-pip package to be installed. > Try using "python -m venv --without-pip VENV" I will try that. ... It runs with no output.

I still get that same message if I try to set up the venv by not using "--without-pip". I offer thanks to Doug and also Andrey who I didn't reply to yet. - Soren -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
