Error: No version of module jupyter-vuetify is registered

[DavideDeMarchi]

Hi all, I am a big fan of ipyvuetify. Thanks for all your work on it.

I have installed it using the command: pip install ipyvuetify

When executing a simple cell like this:

import ipyvuetify as v
my_select = v.Select(label='Fruits', items=['Apple', 'Pear', 'Cherry'])
my_select

I get this error:

Failed to load model class 'SelectModel' from module 'jupyter-vuetify'

I attachment the result of pip list command: piplist.txt

What can I do to solve the issue?

I can't reproduce it on a local JupyterLab instance. It can be that the frontend runs from a different environment where ipyvuetify is not installed at that hosted JupyterLab service.
