Jupyter_contrib_nbextensions: no nbextensions appear

[rsemenoff]

The configurator page is there, but there are no extensions there, other than the configurator itself.
So I redid the install(in a notebook) , like so :

!pip install https://github.com/ipython-contrib/jupyter_contrib_nbextensions/tarball/master

with the following results :

These extension would definitely be very nice to have, so any clues are appreciated.

Did you also follow the second step of the install, to copy CSS/js into jupyter data directory?

See https://github.com/ipython-contrib/jupyter_contrib_nbextensions#2-install-javascript-and-css-files for details

[rsemenoff]

Yes, I did. But ultimately it solved itself by me doing a fresh install of everything.

In my case it was issue with installation using Anaconda :
conda install -c conda-forge jupyter_contrib_nbextensions

I had solved this issue by running pip installation commands:

pip install -e jupyter_contrib_nbextensions
jupyter contrib nbextension install --user

Thank you, it works.

For conda users: If you don not want to mix conda and pip "installations", simply removing (renaming) the directory
~/.local/share/jupyter
works too. (in linux of course)
