Question

Example Jupyterlite notebook in docs doesn't connect to a kernel

Closed this issue 2 months ago · 1 comments

Description

The example notebook embedded in "configuration" in the docs doesn't work for me.

Reproduce

Go to configuration page: https://jupyterlite-sphinx.readthedocs.io/en/latest/configuration.html
Try to use the jupyterlite notebook.
For me it says kernel unknown

Expected behavior

I would expect it to work

Context

Here's one of the errors from the dev tools console:

There's been many releases of Jupyterlite sphinx and pyodide since this issue. I don't think it should be a problem anymore.

I'm going to close, If this is still an issue, please comment so we can reopen, and if there is no answers, please open a new issue referencing this one.

Thanks,
