deprecated and will be removed in a future major version of JupyterLab.

[GWilfred]

I execute the following lines for the local installation

Activate jlab extensions

jupyter labextension install @jupyterlab/toc --no-build
jupyter labextension install @jupyter-widgets/jupyterlab-manager --no-build
jupyter labextension install plotlywidget --no-build
jupyter labextension install jupyterlab-plotly --no-build
jupyter lab build

I got these warnings

What is the workaround to install the required packages?

Hi @GWilfred, thanks for bringing this to my attention. We are currently in the process of upgrading the environment.

Tagging @mmcky in case he can check on what to do with the deprecated jupyter labextension

[doctor-phil]

Hi @GWilfred, can you pull the latest changes from main and try building again?

[mmcky]

@GWilfred if you are using the anaconda python distribution you can create the same environment that the lectures use to run for the website by executing

conda env create -f environment.yml

using the environment.yml file at the root level of this repository.

You will then be using the same software that is tested against the website.

re: your issue above.

It looks like your Jupyter lab may be on an older version than is needed for the extensions you are trying to install?
