[Python-modules-team] Bug#927117: ModuleNotFoundError: No module named 'jupyter_nbextensions_configurator'

[mando at april.org]

Package: jupyter-nbextension-jupyter-js-widgets
Version: 6.0.0-3
Severity: important

Dear Maintainer,

Since the upgrade of jupyter-nbextension-jupyter-js-widgets, it is not
possible to access the parameter tab related to notebook extensions.

   * What led up to the situation?

I've updated jupyter packages

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I ran jupyter-notebook:

   * What was the outcome of this action?

$ jupyter-notebook Intro\ to\ Jupyter\ Notebooks.ipynb
[I 10:58:00.586 NotebookApp] Writing notebook server cookie secret to
/run/user/1000/jupyter/notebook_cookie_secret
[W 10:58:00.897 NotebookApp] Error loading server extension

    Traceback (most recent call last):

        mod = importlib.import_module(modulename)
      File "/usr/lib/python3.7/importlib/__init__.py", line 127, in

        return _bootstrap._gcd_import(name[level:], package, level)

      File "<frozen importlib._bootstrap>", line 965, in
_find_and_load_unlocked
    ModuleNotFoundError: No module named 'jupyter_nbextensions_configurator'

This bugs seems to be related to:
https://github.com/jupyter/notebook/issues/4047

   * What outcome did you expect instead?

We should see in the jupyter main menu a tab allowing to enable/disable
extensions. Currently this tab does not appear due to this error.

Thanks,
Best regards
mando
