[SOLVED] Jupyter Notebook runs fine but Jupyter Lab crashes

Jupyter Lab keeps on crashing everything I run it. Jupyter Notebook runs fine:

[arnuld@arch64 ~]$ jupyter-lab

[arnuld@arch64 ~]$

It complains about Jupyter packaging version which is older than what is available with pacman. Also, I have nothing installed in my ~/.local, no bin and lib there:

[arnuld@arch64 ~]$ ls ~/.local/
share/

[arnuld@arch64 ~]$ which pip
/usr/bin/pip

[arnuld@arch64 ~]$ which jupyter-lab
/usr/bin/jupyter-lab


[arnuld@arch64 ~]$ pacman -Q jupyterlab
jupyterlab 3.0.12-1

[arnuld@arch64 ~]$ pacman -Q python-jupyter_packaging
python-jupyter_packaging 0.8.0-1

I have removed all python and jupyter related files and directories in my ~/.cache and ~/.config but still problem persists.

Re: [SOLVED] Jupyter Notebook runs fine but Jupyter Lab crashes

I am also having trouble with jupyterlab. It seems the python-jupyter_packaging needs to be updated.
When I run jupyter lab build, I get this:

Traceback (most recent call last):
  File "/usr/lib/python3.9/site-packages/pkg_resources/__init__.py", line 568, in _build_master
    ws.require(__requires__)

pkg_resources.DistributionNotFound: The 'jupyter_packaging~=0.7.3' distribution was not found and is required by jupyterlab

As you can see, it is looking for 0.7.3 version while the updated version is 0.8.0.. I haven't tried downgrading the package hoping there might be another jupyter update.

Re: [SOLVED] Jupyter Notebook runs fine but Jupyter Lab crashes

Same problem here. I downgraded to jupyter_packaging 7.12 and it now works.

(If it can help someone: 

sudo pacman -U /var/cache/pacman/pkg/python-jupyter_packaging-0.7.12-1-any.pkg.tar.zst

)

Re: [SOLVED] Jupyter Notebook runs fine but Jupyter Lab crashes

Someone has opened a bug report on this: FS#70142. For now, I will wait for it to be solved.

Re: [SOLVED] Jupyter Notebook runs fine but Jupyter Lab crashes

I can confirm with the latest updates jupyter lab build ran without problems anymore. Fixed.

Thanks arojas for the quick fix! (And also thank you for all the packaging work related to jupyter and sagemath, extremely useful to me.)
