Environment variables persisted #24875
Description
Type: Bug
Behaviour
I switched virtual environment tools for a project from venv to conda but extensions which used python such as ruff continued to reference the old environment. After hours of digging I found a envVar.txt in the extensions directory which contained environment variables referencing the old and now deleted venv directory. This was resulting in virtual environment configuration for ruff to fail due to the removed venv directory.
Steps to reproduce:
- Install Python and Ruff extensions and conda
- Create a python workspace and configure ruff (see config below)
- Setup a venv in the shell for the project under VS Code
python -m venv venv - Activate the environment
source venv/bin/activate - Change
Default Env Managermanager for the workspace toms-python.python:conda - Select a conda environment
A basic pyproject.toml which enables ruff:
[tool.ruff]
required-version = ">=0.9.9"
line-length = 100
[tool.ruff.lint]
select = ["ALL"]The fix was to remove the old deactivate directory, but this was very hard to find as it wasn't associated with workspace in any way.
Diagnostic data
No relavent information from python, error was in the Ruff log, failing to configure python extension as it was trying to run the activate from the old environment.
