Getting the same issue here - did you manage to figure out the cause?

Versions for mine (in case it helps triangulate):

[AdamLuchjenbroers]

Aha - for me the culprit was apparently an older version of jsonschema that had been pulled in as a dependency by another python module.

I am having the same problem in Ubuntu 20.04 in pipenv and poetry envs as well. Any ideas how to fix it?

Downgrading jsonschema from the latest 4.20.0 to 4.19.2 solved the issue for me, fyi.

[gokceneraslan]

@Julian Any suggestions?

[Julian]

How does one reproduce the issue being reported here?

[gokceneraslan]

Running jupyter --version as shown above (or in my case running jupyter-lab) triggers the error when jsonschema 4.20.0 is installed.

[gokceneraslan]

Should this line now also include <4.20.0?

[Julian]

That produces no error here.

Wait, now I updated jsonschema to 4.20.0 and I cannot reproduce the error. I really didn't change anything in between...

[liuchenbaidu]

how to slove it ?

[fengs]

Hit same error

  File "/Users/sophia/.pyenv/versions/3.11.2/lib/python3.11/site-packages/jupyter_events/validators.py", line 44, in <module>

TypeError: create.<locals>.Validator.__init__() got an unexpected keyword argument 'registry'

I solved it by

pip install --upgrade jupyterlab jupyterlab_server jupyter_server traitlets nbformat

as per this post

[weiyunxian80]

@fengs Your answer above solved my issue as well.

[Julian]

I'll just note that running that sort of command is exactly the kind of mistake that's likely to have gotten you into this situation.

Specifically, I claim the only way you could have broken your installation is by running that kind of command!

It's true that running a similar one may get you out of it.

But in Python, it is not safe to run repeated installation commands willy nilly.

pip will not save you from running pip install once and then pip install later in a way that might downgrade a thing you installed. In short: it is a user error if you ever run pip install --upgrade essentially in my opinion, but you doing it twice may indeed fix something (and perhaps break another!).
