virtualenv==20.0.34 not compatible with python on windows #12094
Description
Actual Behavior
virtualenv v20.0.34 fails on windows with anaconda python. virtualenv v20.0.34 introduced a requirement that python have the file <PYTHON_DIR>/Lib/venv/scripts/nt/python.exe. Anaconda python packages do not have this file.
Traceback
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\<redacted>\\python-3.7.9\\Lib\\venv\\scripts\\nt\\python.exe'

Expected Behavior
anaconda python & virtualenv==20.0.34 should be compatible.
Steps to Reproduce
On windows, create a conda environment with python and virtualenv==20.0.34, then try to create a virtualenv
conda create -n foo python virtualenv==20.0.34
conda activate foo
virtualenv ./bar

I also ran into this, since it breaks pre-commit. I can confirm that downgrading to virtualenv=20.0.33 removes the issue.

virtualenv issue to officially support conda due to this problem.

Does anyone know why conda does not follow CPython on the venv creation? Why is custom patched?

Does anybody know what's going on with this question? I used 'Pipenv' in my development, which relies on 'Virtualenv', and now I can't use it properly in my new environment, which annoys me.

FYI: Starting tomorrow, Conda will be broken on Windows for every maintained version of Python. (This will hold true for any virtualenv released in the last 3 years.)
