Extension launching fails: Failed to resolve env

[CharlesGaldin]

Type: Bug

I am using several devcontainers and the python extenstion inside them.
Inside my container, I fail to launch the python extension because the env used in another one cannot be found in this one:

• i am using poetry to generate a venv in my actual container, it is working fine and is located at /app/workspace/.venv/bin/python
• my other container uses another python env located at /home/airflow/.local/bin/python, and inside my first container the loading of the extension fails. The entire logs is given at the end.

However, i can fix this issue by setting the python locator to "js" in my settings: "python.locator": "js", but need to rebuild each one of my containers with this option...

Can you try running the command “Python: clear cache and reload” from the container to see if it behaves better?

Please also share the logs from: Output > Python Locator

[CharlesGaldin]

Hello,

Seems like I cannot reproduce this problem that had been bothering me for at least two weeks before I posted this issue...
Maybe I changed something in my "airflow" container that fixed the problem.

Thank you anyway, and sorry for the inconvenience.

[karthiknadig]

This issue can occur due to some caching bug in the python extension. I am trying to narrow it down, but it has been one of those bugs that is hard to reproduce. If it does occur again, try Python: clear cache and reload command from the command palette, it should help.

[CharlesGaldin]

Hello again,

I faced this issue once more, here are the logs from Output > Python Locator if you want to do anything.
However the command "Python: clear cache and reload" solved my problem immediately, so thank you for that !

@CharlesGaldin Did you try running Python: Clear cache and Reload ?
