python3.exe missing on windows when creating a virtualvenv

[mortenb-buypass]

Issue

I mainly develop for linux on a windows so all my scripts start with #!/usr/bin/env python3

I created a precommit hack for git and it fails on the shebang python3 not found This is the first ever I've seen
the shebang being used on windows. So I discovered it was not there :-)

We have lots of legacy system with legacy python pointing to old version2 python, and -m venv creates a python3 softlink on linux

So it would be nice if they where the same.

I see I do not have a python3.exe under windows main python either, but how can we assure same file will run same binary

Environment

Provide at least:

• OS: windows11
• pip list of the host python where virtualenv is installed:

pip list
Package Version
------- -------
pip     24.2

Output of the virtual environment creation

Make sure to run the creation with -vvv --with-traceback:

workaround

# just go into the rancher
cd C:\dist\venvs\ranchercli\Scripts\

I just checked 3.12.6 venv on ubuntu 22.04 and it has python3:

(ranchercli) mobj@BPOIMOBJ1:/dist$ python3 --version
Python 3.12.6
(ranchercli) mobj@BPOIMOBJ1:/dist$ ls -l ~/.venv/ranchercli/bin/
total 36
