No module named ipython_genutils

[john-science]

My automated GitHub Actions builds that pull nbsphinx are now all failing with the error:

Extension error:
Could not import extension nbsphinx (exception: No module named 'ipython_genutils')

(We are using the most recent nbsphinx==0.8.8.) Is this a known issue? Do you have any advice?

Feel free to see a recent build here.

I am facing a similar issue in my ReadTheDocs build

This bug may have been fixed in some downstream repository?

@jaidisido Is this fixed in your ReadTheDocs build?

See also #638, jupyter/nbconvert#1725, jupyter/nbconvert#1726.

The dependency was dropped in nbclient yesterday (https://github.com/jupyter/nbclient/releases/tag/v0.5.13), which broke nbconvert, which still depended on ipython_genutils.

This was quickly fixed in jupyter/nbconvert#1727 and a new nbconvert release has been made: https://github.com/jupyter/nbconvert/releases/tag/6.4.3.

Now everything should be working again.

I guess in most cases it should work automatically, but if not, you can try to specify nbconvert>=6.4.3.

@mgeier Thanks so much for the information!
