Pure Python Wheel #750

Closed petrushy closed 2 years ago

petrushy commented 2 years ago

It would be nice to be able to use skyfield from pyiodide or jupyterlite, but this seems to require a "pure-python wheel" in the pypi. It breaks on the sgp4 dependency. As I understand this is mostly some build parameters.

https://jupyterlite.readthedocs.io

The import code in jupyterlite: import piplite await piplite.install([ 'skyfield'], keep_going=True)

gives

...

ValueError: Couldn't find a pure Python 3 wheel for: 'sgp4>=2.2'

Alas, sgp4 isn't a pure Python library; it embeds a C++ library. Could you open an issue over in its GitHub repository where we could investigate what will be necessary to get it working on that platform?

Thanks!
