Pyenv virtualenvs not showing in `Python: Select Interpreter` command palette option

[paluchasz]

Type: Bug

Behaviour

Today (7th July 2025) I performed a VScode update (to the June release I think). Before the update when I went to the VS Code command palette - Python: Select Interpreter I could see a full list of pyenv options including my custom virtual environments with custom names. After the VScode options all my virtual environment options are missing from the list and all I see is the the pyenv default installed python versions.

This is a screenshot of the issue.

Unfortunately, I do not have a screenshot of when it was working. Please note for this project it correctly suggests the .venv file, however the issue is for projects which use a pyenv-virtualenv instead.

Additionally, when I try to manually enter the interpreter path and point it to the correct virtualenv (and bin/python) it doesn't select it either.

Steps to reproduce:

Install pyenv and pyenv-virtualenv. I followed this guide in the past: https://realpython.com/intro-to-pyenv/.

Install a Python version with pyenv. E.g.

pyenv install 3.11.9

Create a virtualenv with Pyenv with the name test, for instance:

pyenv virtualenv 3.11.9 test

Go to VSCode command palette and Python: Select Interpreter. The virtualenv test should appear as one of the pyenv options in the list to select.

I have the exact same issue

[nilbest]

I can not select any Interpreter, and also it will not even show the global one or the ones added via

python -m venv .venv

.

But if I hop into the cmd, activate the venv, and start my program from there it works. But directly throw VSCode it doesn't. Also, the status bar does not show any interpreter but VS Code auto detects Python as a language.

Also if I try to add the direct path of the interpreter directly threw the settings it will still not run. For me it seems like it does not find any interpreter at all also if you give it the direct path to a venv or global Python one it does not use it.

Same problem with the Jupyter extension as well.

I also updated to 1.101.2.
Also tried to reinstall 1.100.3 and used Python 3.13 and 3.11 nothing worked for me.

Edit:
Reinstalling 1.101.2 did the Trick. I had to reinstall it but I had to use the System installer Version, not the User installer Version. But I still have no idea why the update broke my VS Code in the first place.

Hello! Can you check if you see a python logo in your sidebar? We are rolling out our new extension that handles environments and my guess is this is what caused the behavior change but want to confirm. Thanks

[paluchasz]

Hi, thanks for your answer. Today I noticed another VSCode update (now I am on version 1.102.0 rather than 1.101.2 like when I made the ticket) and it seems the issue is resolved. And yes I see the Python logo in the side bar.

I guess I will close it and reopen if the issue comes back!

Is this a new issue?
i didn't have this issue until a few weeks ago.
usually I didn't even need to have pyenv in my .zshrc path, it just automatically detected it from the get go, but now i cant even select pyenv to create virtualenvs with via vscode, what am i missing?

{
  "python.venvPath": "${env:HOME}/.pyenv/versions",
  "python.defaultInterpreterPath": "~/.pyenv/shims/python",
  "terminal.integrated.defaultProfile.osx": "zsh",
  "python.terminal.activateEnvironment": true
}

Update on this, removing the auto added Python Environments Extension resolves this.

actually going to move discussion to this issue as it seems the same so I can gather all information and communicate there. Please let me know if you do not think these issues are the same, thanks
