Update to the new `empack`

[jtpio]

Problem

A few projects in the emscripten forge organization have now been updated to use the new empack >=3.0.0:

• https://github.com/emscripten-forge/pyjs-code-runner
• https://github.com/emscripten-forge/sample-python-repl

Proposed Solution

Update the xeus python kernel to empack>=3.0.0.

This will likely require the next version of jupyterlite-xeus-python to be 0.9.0.

Additional context

This may help me finish https://github.com/conda-forge/staged-recipes/pull/22492 as well, because it may help supporting Windows

for that, we need a new release /tag in of xeus python (with this in https://github.com/jupyter-xeus/xeus-python/pull/588) Then we can put that version on emscripten-forge Once we have that we can use the whole empack >= 3.0.0 stack here

for that, we need a new release /tag in of xeus python (with this in jupyter-xeus/xeus-python#588)

@martinRenou or @DerThorsten would you be able to make a new release of Xeus Python? Thanks!

Nice thanks!

Just opened https://github.com/emscripten-forge/recipes/pull/449

[JeongJun-Lee]

is the reason why I met this error on the jupyter lite build command: FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/opt/python@3.10/Frameworks/Python.framework/Versions/3.10/share/empack/empack_config.yaml'?

[martinRenou]

@JeongJun-Lee I think this is unrelated, would you be able to open your own issue with more in-depth information about your setup, like the empack version and how you installed it?

Closing as fixed by https://github.com/jupyterlite/xeus-python-kernel/pull/134, thanks!
