The recent upgrade to some part of jupyter have broken py310-notebook (and 311 and 312)

There are a few other open jupyter ticket that might be related?

Any help getting notebook to run would be appreciated.

This bug has been here for several weeks.

To me, editing (for 3.11, modify your version).

/opt/local/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/notebook/traittypes.py 

And manually changing

from traitlets import ClassBasedTraitType, Undefined, warn

to

from warnings import warn
from traitlets import ClassBasedTraitType, Undefined

makes it work. This looks better to me than installing the package via pip.

pip uninstall traitlets
pip install traitlets==5.9.0

as mentioned in other reports.

For the traitlets issue ​https://trac.macports.org/ticket/69244 I was able to just go back to the older version of traitlets from Macports. (I downloaded the 5.9 portfile) and that was a good workaround.

So, I'm still using 5.9 but as of yesterday, with an upgrade in jupyter (-lab? Notebook? some other piece?) I can get notebook to open.

so I don't think that this is the same as the few week old one that you mentioned.

I tried the edit that @albcn suggested and I still get the same error when I try to startup jupyter-notebook. So, this is not the same.

I implemented the patch suggested by @albcn in ​https://github.com/macports/macports-ports/pull/22859
