This repository doesn't 'just work' about jupyterlab-feedstock HOT 4 CLOSED

Wow, thank you so much.

Sorry old memory betrayed me.

mamba install jupyterlab ipywidgets tqdm

from jupyterlab-feedstock.

The marquee feature of JupyterLab 3 is basically: the end user of pip or conda does not need nodejs or access to npmjs.com, and jupyter labextension install is not required for an increasingly large swathe of extensions. Each pip package deploys the pre-built files to $CONDA_PREFIX/share/jupyter/labextensions. By extension, conda-build should not even need to invoke nodejs, or contact npmjs.com during the build.

For ipywidgets, in specific, the jupyterlab 3 assets are delivered by its dependency jupyterlab_widgets. I personally prefer this pattern, but the pattern of distributing client assets (to be used by the server) along with kernel assets (e.g. the python widget classes) is probably here to stay unless we can figure out a clever pattern.

In short, with jlab 3, you just mamba install ipywidgets and jupyterlab and you are done. No need to install nodejs or your last two lines above. Just

mamba install ipywidgets jupyterlab

from jupyterlab-feedstock.

Let me try
