Trying to run jupyter lab from prompt yields "Segmentation fault:11"

To help you compose your answer:
I am a naif, a very new beginner person with all things coding.
I am trying to use jupyter lab in order to learn Python in order to raise my geographic information system (GIS) map-making skills. (I use QGIS.)
I came to jupyter lab through the University of Helsinki free online course “Geo-Python”.
I understand human language well (native English, pretty good with Spanish).
But I do not understand most of the terms I see members posting here.
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Using a MacBook Pro on which I run OS Mojave (10.14.2).
I just installed jupyter yesterday (Thursday the 27th of April 2023); I don’t know what version that makes me, but it’s “fresh” today.
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
The question
When, in the Mac terminal window, I type “jupiter lab” at the prompt (as directed in the Un.of Helsinki course material), the result is
Segmentation fault: 11

How do I get past this and get jupyter lab to run?

Thank you.

It appears that someone else is experiencing this very recently as per report on: conda - JupyterLab Packaging (jlpm) Segmentation Fault - Stack Overflow and they are also using MacBook. Did you install jupyter from conda-forge, or in a different way? If so would you be happy to provide a full conda list?
Could you try running jupyter lab --debug and list all output prior to the crash (if any)?

Thank you for responding.
I think I did use conda-forge, now that you mention it.
I ran jupyter lab --debug and got
(base) MacBook-Pro-2:~ Cogreg$ jupyter lab --debug

Segmentation fault: 11

(base) MacBook-Pro-2:~ Cogreg$

The conda list follows.

(base) MacBook-Pro-2:~ Cogreg$

Same issue here, since today, also with Mac OSX Mojave (10.14.6).
Yesterday I ran conda update jupyterlab and I updated the macport packages.

Here are the packages I share with cogreg, with same version and build (all from conda-forge)

boltons                        23.0.0     pyhd8ed1ab_0
ca-certificates                2022.12.7  h033912b_0

jsonpatch                      1.32       pyhd8ed1ab_0
jsonpointer                    2.0        py_0

Can anyone help me with this, please?

i don’t use macos nor conda, but as far as i understand the problem, you can only hope this gets fixed in conda forge dependencies.

in the meantime an alternative would be to try to install jupyterlab via pip install jupyterlab

See https://github.com/conda-forge/jupyterlab-feedstock/issues/378

You can recover a working environment with last jupyterlab version by pinning libffi to 3.3.

micromamba create -f https://prefix.dev/envs/marcbernot/mojave/conda-lock.yml -n mojave
or
conda create -n testmojave python=3.9 libffi=3.3 notebook jupyterlab.
See more details here.

I have same problem…

ISSUE segmentation fault

SYSTEM Mac Mojave 10.14

Conclude some version does not support Mojave 10.14; I cannot upgrade above 10.14
likely conda itself since I have been updating it; can I revert to an older conda?

Goal create an env; jupyterlab pandas scikit-learn matplotlib -with dependancies like python,
numpy, etc

SUMMARY
I created many envs (in order of occurance as follows), then try to launch jupyterlab:
new1 install jupyterlab pandas scikit-learn matplotlib
#> 5959 segmentation fault
#> 5818 segmentation fault
#> 6019 segmentation fault (debug)
test install jupyterlab=3.6.6 pandas scikit-learn matplotlib
#> 2389 segmentation fault
#> 2443 segmentation fault (debug)
test2 jupyterlab=3.5.3 pandas scikit-learn matplotlib
#> command not found: jupyterlab
#> 4165 segmentation fault (debug)
test3 jupyterlab=3.5.3 python=3.11.0 scikit-learn matplotlib
#> 5080 segmentation fault
#> 5124 segmentation fault (debug)

datails below:

test3 jupyterlab=3.5.3 python=3.11.0 scikit-learn matplotlib

jupyterlab 3.5.3
numpy 1.26.2
pandas 2.1.4
python 3.11.0

❯ jupyterlab #> 5080 segmentation fault
❯ jupyter lab --debug #> 5124 segmentation fault

test2 jupyterlab=3.5.3 pandas scikit-learn matplotlib FAIL
install jupyterlab=3.5.3 pandas scikit-learn matplotlib
jupyterlab=3.5.3
matplotlib-3.8.2
numpy-1.26.2
pandas-2.1.4
scikit-learn-1.3.2
scipy-1.11.4
python 3.12

❯ jupyterlab #> command not found: jupyterlab
❯ jupyter lab --debug #> 4165 segmentation fault

test jupyterlab=3.6.6 pandas scikit-learn matplotlib FAIL
looks like this installed a lot of new packages; I wrongly assumed it would instal packages from the same jupyterlab 3.6.6 ‘era’
❯ conda install jupyterlab=3.6.6 pandas scikit-learn matplotlib
❯ conda list # to see pkgs installed
INSTALLED SUM; main packages
jupyterlab 3.6.6
pandas 2.1.4
numpy-1.26.2
python-3.11.7
matplotlib 3.8.2
scikit-learn-1.3.2
scipy-1.11.4

❯ jupyter lab #> 2389 segmentation fault :heavy_multiplication_x:
❯ jupyter lab --debug #> 2443 segmentation fault

new1 install jupyterlab pandas scikit-learn matplotlib
#> 5959 segmentation fault

no longer have the doc for this since I deleted it
