Failed to find a compatible python environment at the configured path (3.3.2-2+)

Description

With the latest release (v3.3.2-2) of Jupyterlab Desktop, I can’t use python env created by conda. It prompted with the following message. With v3.3.2-1, I didn’t have any issue.

failed to find a compatible python environment at the configured path “/users/p.xing/library/jupyterlab-desktop/jlab_server/bin/python”. environment python package requirements are: jupyterlab >=3.1.0.

Reproduce

• Install the latest v3.3.2-2
• activate python env with conda activate jupyterlab
• get python dir which python
• Use the prompted path /Users/myUserName/miniconda3/envs/jupyterlab/bin/python as the Jupyter lab desktop custom env path
• failed to boot

Expected behavior

(pre) Solution

Using the v3.3.2-1 pkg installer, boot up with no issue.

Can also confirm that this is similarly broken on M1 Pro. It is impossible to switch environments from conda to pip. The system never recognizes my virtualenv with jupyterlab installed. It works just fine on my Intel Mac Mini.

I cannot use Jupyter Desktop at all since Conda is a nonviable environment for us.

Jupyter installed via homebrew, using the instructions above, works.

Hi. I upgraded from jupyterlab-app (3.1.12-1) to jupyterlab-desktop (3.3.4-2) on my Debian Linux laptop and got this error too.

Set Python Environment
Failed to find a compatible Python environment at the configured path "/home/adam/.config/jupyterlab-desktop/jlab_server/bin/python". Environment Python package requirements are: jupyterlab >=3.1.0.

I ran mv ~/.config/jupyterlab_app{,.bak} after removing jupyterlab-app (3.1.12-1). I am trying to use a conda env Python3 too. conda is alreay in my PATH, which can be confirmed by running conda activate sklearn-env to get a working python 3.9.13 env.

I tried launching in a terminal with /opt/JupyterLab/jupyterlab-desktop command after I activated the conda Python3 env but the same error persisted. This is ~/.config/jupyterlab-desktop/logs/main.log :

See the line

[2022-08-04 18:32:38.927] [error] (node:791112) UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory, scandir '/home/adam/Programs/miniconda3/envs/sklearn-env/envs'

It’s definitely looking for the wrong thing, where I was told to choose a the path to python (in my case /home/adam/Programs/miniconda3/envs/sklearn-env/bin/python3), but it’s somehow looking for a env? I may have to set /home/adam/Programs/miniconda3/envs/ at Use a custom Python environment but it won’t let me choose a path to a dir. Help this helps.
