Support for recent nbconvert and traitlets

[fdion]

Issue #92 raised the problem a few years back. The solution was to freeze nbconvert and traitlets. This is not practical anymore, and hide_code needs compatibility with more recent versions (at least 6.x for nbconvert)

#98 is also related.

Same problem here!

I've started working on a code base that includes a Jupyter Notebook setup to run in Binder and have encountered this issue too.

We have in our requirements.txt...

hide_code>=0.5.2
ipysheet>=0.4.4
ipywidgets>=7.6.3
jupyterlab>=3.0.15
jupyter_contrib_nbextensions

...which pulls in hide_code-0.6.0 which requires nbconvert<6 (from setup.py. traitlets-4.3.3 is also pulled in as a consequence which also seems a bit dated (current version on PyPi appears to be 5.2.2).

Install logs then go on to show that a bunch of packages are downgraded because of a conflict between nbclient-0.5.13...

 ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
nbclient 0.5.13 requires traitlets>=5.0.0, but you have traitlets 4.3.3 which is incompatible.

So I figured I'd try out specifying a minimum version of nbclient>=0.6.4 and what do you know, it only goes and works!

My current requirements.txt for this are as follows, I hope others find it useful in the meantime.

hide_code>=0.5.2
ipysheet>=0.4.4
ipywidgets>=7.6.3
jupyterlab>=3.0.15
jupyter_contrib_nbextensions
nbclient>=0.6.4
