Missing or misshapen translation settings schema

[taktikal17]

I am getting an error when launching jupyter.
I uninstalled everything including python (with brew) and still not solving the issue.

The folder /opt/homebrew/Cellar/python@3.11/3.11.4_1/Frameworks/Python.framework/Versions/3.11/share/
doesn't contain the jupyter folder.

Here the lib I am ussing:

ipykernel==6.24.0
notebook==7.0.0
notebook_shim==0.2.3
Python 3.11.4

Jupyter lab would work using
jupyter lab --app-dir /opt/homebrew/share/jupyter/lab

How do I change the path to run jupyter notebook?

Thank you

Thanks @taktikal17 for reporting the issue 👍

Jupyter lab would work using

Just to confirm: does JupyterLab work without specifying the --app-dir option?

I am seeing something similar, also possibly with some weird interactions with jupyterlab. (I think on one of my machines it is failing at a different *.json schema than in this traceback, but I don't have access right now.)

Also possibly related:

• the “Open in…” (used to be called “Interface”, I think?) menu does not appear
• In the file list window which opens from jupyter notebook, the “File” menu ends with “Save and export notebook as…” – it is missing “Trust notebook”, “Close and Shut Down Notebook”, “Log out” and “Shut Down”.

same issue here, notebook version 6.5.4 had no issue.

If one of you has a Mac and would be able to look into this that would be great, thanks 🙏

A further possibly useful bit of info:

On my setup, Python 3.11 is installed by homebrew, but all packages, including jupyter, notebook, etc. are installed with pip.

[defjaf]

I note that

JUPYTER_PATH=/opt/homebrew/share/jupyter JUPYTER_CONFIG_PATH=/opt/homebrew/etc/jupyter jupyter notebook

is a partial fix: it still gives error messages in the terminal, but the interface issues mentioned above seem to be better.

So it is possible that this is an issue of "miscommunication" between the homebrew build and jupyter?

[defjaf]

Further to my previous partial fix using JUPYTER_PATH and JUPYTER_CONFIG_PATH

I note that in fact jupyter lab behaves better with those environment variables set as above: without them, it does not seem to correctly recognise extensions. (To be precise, app-dir does not solve these problems.) So I wonder if we need to make this a broader issue?

In detail: without the variables set, the "Installed" list is empty and, for example, there is no sidebar entry for ipyparallel even when installed:

---

When run with those variables set, I get:
