Template does not work

[StasJ]

This template is currently broken and does not work with Jupyter Lab. The typescript template (jupyter-widgets/widget-ts-cookiecutter) is working.

Any details on what is broken about it?

Also, you might want to consider using AnyWidget instead of this template.

If you follow the instructions in the README you will get a javascript error in place of a widget when attempting to use it in Jupyter Lab

Also, you might want to consider using AnyWidget instead of this template.

Thank you for the suggestion, however, we already have a completed widget built with an earlier version of the template, and the AnyWidget REAME warns it is not ready for production. Next time I hope to use that instead as it seems like a simpler solution.

This is what the error looks like in classic notebook.

The lab dev instructions simply fail to build.

By the way this is the same symptom I see with my own project https://github.com/AaronWatters/jp_proxy_widget
which is why I came here....

I think the dev build works, but not the production when the python and javascript package have different names.

For me the template does not work at all. I've followed religiously the instructions and cannot execute steps like

jupyter labextension develop --overwrite jupyter_widget_example

I receive errors of the kind package.json not found in directory jupyter_widget_example
