Python interpreter is not the one at the virtualenv

[captainepoch]

Hello!

Thank you for making this project, I was looking for an easy way to deploy a local development environment on NixOS for the ESP32.

After installing it within a default.nix and to get it working with direnv, I ran the command idf.py --list-targets, and this is the output:

$ idf.py --list-targets
WARNING: Python interpreter "/nix/store/27g99bzyxayxaiifyryi3g9vyqi3zrac-python3-3.11.10-env/bin/python3.11" used to start idf.py is not from installed venv "/nix/store/my7axvf10k7vr63l6j0fydvw5h68df8k-esp-idf-v5.3.1/python-env"
esp32
esp32s2
esp32c3
esp32s3
esp32c2
esp32c6
esp32h2
esp32p4

Is this expected? Shouldn't the virtualenv load the interpreter within it?

Again, thank you!
