Issue Enabling Jupyter Notebook Extensions on TLJH

JupyterHub The Littlest JupyterHub
1

Hello!

First thanks to all contributors for maintaining this project.
I successfully installed TLJH on my server following the official documentation. While enabling extensions for all users as per this guide, I encountered the following issue when running:

sudo -E jupyter contrib nbextension install --sys-prefix

error

sudo -E jupyter contrib nbextension install --sys-prefix
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/dist-packages/jupyter_contrib_core/notebook_compat/nbextensions.py", line 6, in <module>
    from notebook.extensions import BaseExtensionApp
ModuleNotFoundError: No module named 'notebook.extensions'

After some research, I downgraded Jupyter Notebook to 6.4.12, which resolved the error. However, after restarting, the notebook UI does not display any indication that the extensions(spellchecker,scratchpad in the example etc) are available.

System Details:

  • JupyterHub: 5.2.1
  • Jupyter Notebook: 6.4.12

Note: The X are due to my unsuccessful attemps to install nbextensions_configurator

Would be very appreciated if anyone could offer some hints or troubleshooting guidance, thanks.
