Widget Javascript not detected v5.2.2

See original GitHub issue

I’m running ipywidgets 5.2.2 on Windows, Python 3.6, and:

  • Jupyter 1.0.0
  • Jupyter_client 5.0.1
  • Jupyter_console 5.1.0
  • Jupyter_core 4.3.0

and encounter this issue:

[IPKernelApp] WARNING | Widget Javascript not detected.  It may not be installed
 properly. Did you enable the widgetsnbextension? If not, then run "jupyter nbex
tension enable --py --sys-prefix widgetsnbextension"

Also Widgets are not shown in the Notebook.

Running jupyter nbextension enable --py --sys-prefix widgetsnbextension doesn’t solve the issue.

Thanks.

Can you either:

  1. upgrade to ipywidgets 6 (compatible with widgetsnbextension 2.0), or even better, ipywidgets 7 and widgetsnbextension 3
  2. Downgrade widgetsnbextension to 1.2.6
