Can't import hvplot.pandas

Complete, minimal, self-contained example code that reproduces the issue

import hvplot.pandas

Problem description

When I try the import, I get the following response in a Jupyter Notebook on Chrome or Edge:

Javascript error adding output!
Error: Cannot find module '@bokehjs/styles/buttons'
See your browser Javascript console for more details.

With Internet Explorer, I get the following (both messages):

Javascript error adding output!
SyntaxError: Expected ';'
See your browser Javascript console for more details.

Javascript error adding output!
SyntaxError: Syntax error
See your browser Javascript console for more details.

After that, any calls to hvplot produce no output.

Thank you! If this is a bokeh issue rather than an hvplot issue, please advise.

[Hoxbro]

Try updating panel to the latest version with this command conda install panel=0.11 -c pyviz

[stualden]

Thank you everyone - I’m grateful for your help, and once again a happy hvplot user.
