Unable to use jupyterlite-sphinx with Jupyterbook after package upgrades (anymore)

Question

Unable to use jupyterlite-sphinx with Jupyterbook after package upgrades (anymore)

Closed this issue a year ago · 3 comments

Description

Due to some version upgrades (unfortunately I can't remember the previous system states on packages), I am no longer able to use jupyterlite-sphinx with Jupyter Book. I was able to get this working before I did some package upgrades but am not able to reproduce:

Reproduce

Here are some steps to reproduce:

Clone this repo: git clone https://github.com/firasm/jb_jblite_jupyterlabdeck.git
Run Jupyterbook: jb build jb_jblite_jupyterlabdeck

Expected behavior

I expect Jupyterlite to be embedded into my JupyterBook.

Context

The error seems to occur because "jupyter-lite" cannot be found:

Would love any assistance to get this working!

Answer 1 · 2023-04-02T08:43:39.000Z

Thanks @firasm for the report.

I just tried in a fresh new environment (on Gitpod) with:

pip install jupyter-book jupyterlite-sphinx
jb build .
python -m http.server

And it seem to build fine:

Also note that with newer versions of jupyterlite-sphinx you need to install a kernel explicitly: https://github.com/jupyterlite/jupyterlite-sphinx/blob/main/CHANGELOG.md#080

Answer 2 · 2023-04-02T12:31:39.000Z

Hmmm okay thanks a lot for the sanity check @jtpio - I was able to reproduce it working on gitpod.

Locally, I tried creating a fresh environment after (uninstalling a bunch of packages):

python -m venv fresh3
pip install jupyter-book jupyterlite-sphinx jupyterlite-pyodide-kernel

But now I get a different error ("Kernel died") while trying to build the book (so, progress I guess!):

Okay I have solved this finally! The error above was arising because I created a venv inside my jupyter book directory which caused files in the directory to be parsed and resulted in errors.

I still have the Jupyter command jupyter-lite not found. in my main environment despite doing pip freeze in my fresh environment and installing those packages in my main environment but it's clear there's some weird interaction somewhere that's cause an issue.

Anyway since I have things working with a fresh environment I'll close this issue and see if I can resolve the main issue another time.

Thank you for your help and direction to try things in gitpod!!
