Installing ipysankeywidget seems to install an extension file in notebook.d which refers to "ipysankeywidget/extension", which I think is wrong -- it should be jupyter-sankey-widget/extension.
The latter is created in notebook.json when running jupyter nbextension enable --py --sys-prefix ipysankeywidget
