BUG: Can't import hvplot.pandas

[stualden]

Code Sample, a copy-pastable example

# Your code here
import hvplot.pandas

Problem description

When I try the import, I get the following when running from a Jupyter Notebook on Chrome or Edge:

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. I have checked the Javascript console, but it did not illuminate the problem for me.

Output of pd.show_versions()

@stualden This looks like an issue for hvplot, have you tried posting there?

Of course, sorry about that - thank you.
