Python interpreter into a symlink venv does not work on windows #25208

Open
@DATA2PLAYvf

Description

@DATA2PLAYvf

Type: Bug

Behaviour

On windows, when I select a python venv (via Ctrl+MAj+P) or via python.defaultInterpreterPath value, the venv is not catched, and VS Code use the target of my venv python.exe symlink

Steps to reproduce:

  1. on windows, create a venv with python.exe symbolic link instead of copy. You will need admin mode :
    cd c:\temp
    python -m venv --symlink my_venv

  2. create a new VS Code workspace with .vscode/settings.json with the content {"python.defaultInterpreterPath": "C:/temp/my_venv/Scripts/python.exe"}

  3. Edit a python file, you will see that the "python locator" in the bottom blue bar is not your venv, but the default version of python of your system.
