Could not instantiate widget - default folder name convention is wrong #108

Closed daquintero closed 1 year ago

daquintero commented 1 year ago

Hi,

I think the default js/lib naming convention is wrong, and it may have to do with the packaging names between the model instantiation. I say this because I get the error below when building using the default folder name convention and all my files are the same. When I change the lib name to src on all its instances the widget builds.

My suspicion is that it is in the default __init__ _jupyter_labextension_paths names.

It was a dependency problem on errors above on installing ipyevents and ipytree
