Xuanteng (in CC) is working on packages jupyter-cache and myst-nb, both
of which make use of nbdime in their test suites. We were wondering if
you could provide us with a status update for nbdime?

We gave our own brief look, after upgrading nbdime to 4.0.1, but the
build fails because npm tries to download source-map-loader:

> INFO:hatch_jupyter_builder.utils:> /usr/bin/npm install

We've added it [1] and node-jupyterlab [2] to B-D as a stab in the dark,
but that didn't fix it. Unfortunately, we don't have experience with
node stuff in Debian.

Do you have an idea what's going on here? Otherwise I could ask on the
debian-js list.

Best,
Christian
