Can't install jupyterlab in debian-slim

[pamelafox]

Here's my setup:

FROM debian:bullseye-slim

devcontainer.json:

{
	"name": "Data 8 notebooks",
	"build": {
		"dockerfile": "dockerfile",
		"context": ".."
	},
	"features": {
		"ghcr.io/devcontainers/features/python:1": {
			"version": "3.11",
			"installJupyterlab": true
		}
	},

That results in this error:

#18 325.5 ./install.sh: line 307: /usr/local/python/3.11.4/bin/python3 -m pip install --user --upgrade --no-cache-dir jupyterlab: No such file or directory
#18 325.5 ERROR: Feature "Python" (ghcr.io/devcontainers/features/python) failed to install! Look at the documentation at https://github.com/devcontainers/features/tree/main/src/python for help troubleshooting this error.

Notably, I'm intentionally using a Debian that has no built-in Python package, as I'm trying to create an image with a single Python version. So maybe the PYTHON_SRC logic isn't compatible with that?

HI 👋

@alexander-smolyakov can you help investigate? thanks!

@pamelafox In the meanwhile, can you use the mcr.microsoft.com/devcontainers/base:bullseye image instead? Dev container was successfully created with it 👇

Thanks @samruddhikhandale - that does build, but I believe it also has a base Python version from the OS (try running python 3.9). I'm using slim to avoid that, and only have one version.

Also, I haven't managed to get that one to load in Jupyterlab (from "your codespaces" tab), but I'll bring that up with Codespaces team.

Hey @pamelafox, we have merged the fix for the Python feature. Could you please check if the issue is resolved now?
