Update to JupyterLab 4 and Notebook 7 by jtpio · Pull Request #1302 · jupyterhub/repo2docker (original) (raw)

Hmm, the failures look real:

Jupyter command `jupyter-nbextension` not found.

Thoughts on splitting up the upgrade to jupyterlab 4 from notebook 7? I think the jupyterlab 4 change is uncontroversial and easy. But for notebook 7, we have to figure out what to do about nbclassic, and it's a bit more of a breaking change.
