Description

After installing new version of Jupyterlab Desktop (version 4.0.7-1), I cannot start new session since python environment is not found, even when it has been installed (bundled environment).

Reproduce

  1. Launch Jupyterlab Desktop, either from terminal (jlab) or with menu.
  2. See error 'Python environment not found'

Context

  • Operating System and version: Linux Mint 21.2 Cinnamon
  • JupyterLab-Desktop version: 4.0.7-1
  • Installer: .deb
Logs (required for issues with loading, server and startup) The log file in .config/jupyterlab-desktop/logs/main.log gives the following information:

Are you still seeing this with a newer version? Does the problem persist after uninstalling and installing JupyterLab Desktop?

I am not sure if this is related but I have a a similar issue. I have jupyterlab installed in a base conda environemtn and I can run jupyter lab from the terminal as a web application without any issues.

When I launched JLD I was prompted to create a custom environment and I setup the python path to point to python in the base conda environment.

However, JLD will not start now

JLD version: 4.0.7-1 (although this happens on older versions as well)
Mac OS: 13.4.1 running M1 processor
JL version in environment: 4.0.8 (although same happens for any version of JL I've tried, e.g. 3.6.3)

Log file (I have replaced my actual username with a placeholder USERNAME for posting, but on my machine it is just my real username). Note that the first log entry are from a fresh install of JLD and then after being prompted I updated the python path.

hi @rclUPC can you try these on your system terminal. does it work? any error messages?

jlab env activate # assumes you have installed the bundled environment already
jupyter lab

I tried this and it did work in my case, i.e. it launched a jupyterlab web app.

BTW, if I use another python env (f.i., anaconda3) it works fine.

How does it search for jupyterlab?
I have python installed at D:\Program Files\Python312-arm64\python.exe but the installed jupyterlab are at C:\Users\UserNAME\AppData\Roaming\Python\Python312-arm64\ and it cannot find jupyterlab. I also tried sym linking site-packages and jupyter.exe jupyter-lab.exe
