ipywidgets unresolved?

[darkblueb]

the current collection of components for ipython and Jupyter is a mix of newer and older.

Therefore, not all the features of Jupyter Notebook interaction are expected to work perfectly. Notebook interaction is (mostly) replaced by JupyterLab in the future.

But what we ship should be consistant. This test is failing.

from ipywidgets import IntSlider
from IPython.display import display
slider = IntSlider(min=1, max=10)
display(slider)

Widget Javascript not detected.  It may not be installed properly. Did you enable the widgetsnbextension? If not, then run "jupyter nbextension enable --py --sys-prefix widgetsnbextension"

I think "jupyter nbextension" has been replaced by "jupyter-nbextension" in current version
