Status bar shows wrong Python version for selected virtual environment

[ROT-at-OpenEP]

Type: Bug

Behaviour

• Status bar shows wrong Python version for active Python virtual environment "3.12.3 ('.venv')" (corresponding to syestem version) instead of the Python version actually configured in the virutal environment (3.11.9).

Steps to reproduce:

1. Open Visual Studio Code
2. Open workspace folder
3. workspace folder contains virtual Python environment under sub-folder .venv (with Python version 3.11.9)
4. status bar displays "3.12.3 ('.venv')"
5. Ctrl-Shift-P and selecting correct Python environment "Python 3.11.9 (.venv)" does not change status bar to the correct version.
6. Running python code

import sys
print(sys.exectuable)
print(sys.version)

prints the correct exectuble "/path/to/workspace/.venv/bin/python" and the correct version "Python 3.11.9".

7. as well the correct version is shown for the corresponding jupyter kernel whe notebook is opened.
8. VS code integrated Terminal is as well switching into correct virtual environment after launch. and command "python --version" returns "Python 3.11.9".
9. this problem is on a Linux Mint 22.1 but not on Windows 10 Enterprise, both using the same version of VS code (1.100.3). On Linux Mint its installed under "root" account, on Windows under "user" account.

Are you using the Python environment extension? https://marketplace.visualstudio.com/items?itemName=ms-python.vscode-python-envs

No, I don’t use the Python Environment extension. No need for this so far. On linux host, I am using pyenv to install a specific version of Python (e.g., 3.11.9). In the project workspace, I am using virtualenv and pipenv to manage set up virtual python environment and installing packages, respectively. The issue with the status bar is a recent regression, not observed before.

[ROT-at-OpenEP]

Status bar displays "wrong" Python version for activated virtual environment:

Jupyter notebook's kernel, based on activated Python virtual environment displays "correct" Python version:

Running python --version in integrated terminal with activated Python virtual environment (automatically activated by Visual Studio Code) returns correct Python version:

Selecting Python Interpreter via Ctrl-Shift-P shows "correct" Python virtual environment as "recommended" environment. Selecting it (even by switching to some other envrionment temporarily) does not fix the issue:

I hope this illustrates the bug report further.

Morning,

FYI. I set up a new equivalent (Virtualbox) VM with Linux Mint 22.1 and with equivalent Python, Pyenv, Virtualenv, Pipenv, VSCode (and extensions (via settings sync)) etc..

The initially reported issues are not materialising on this VM. All works as expected. I.e., the projecct's Python version displays correctly in code's status bar.

Best.
