add JULIA_PYTHONCALL_EXE=@venv to load python from .venv folder #668
Description
Is your feature request related to a problem? Please describe.
I'd like to disable CondaPkg and use python in manually created .venv
Describe the solution you'd like
add meta config JULIA_PYTHONCALL_EXE=@venv that would load .venv/bin/python or .venv/Scripts/python.exe (on windows).
The folder .venv is at the same folder with (Julia)Project.toml just like .CondaPkg
Additional context
Now we have @CondaPkg (default), and @PyCall, I'd like to add @venv to simplify configuration.

This is a nice idea!

Relatedly, we could also change the env var so that if you pass a relative path, it is interpreted as relative to the current project (instead of the current working directory). This might be breaking though.
For example
JULIA_PYTHONCALL_EXE=.venv/bin/pythonwould be equivalent to@venv(on Unix).cjdoris commentedon Sep 15, 2025
Its a slippery slope but we could also add
@uvwhich is like@venvbut also runsuv syncfirst.
