I am trying to load theskyfield package.
It has one non-pure python packagesgp4.
The author has made a pure python version -sgp4_pure_python which has aprovides tag which says it provides for sgp4.
This package loads successfully on its own butskyfield will not load.

The idea behind this idea is so I could load thesgp4_pure_python package and then loadskyfield
This might then succeed.
At the moment I still get error "no pure python package for sgp4 can be found"

SO

1. Its possible I cannot forcesgp4_pure_python to be loaded beforeskyfield as all is async, or
2. Its possible micropip does not pay attention to theprovides tag insgp4_pure_python package, or
3. Maybe I can fool it by somehow setting thedeps option in micropip.
   • Invoked like this: micropip.install("pkg", deps=False)
   • Is there a way to signaldeps in the toml file ? That might allow me to load the skyfield package.

The problem is documented here (on the skyfield github) -skyfielders/python-skyfield#1040 (comment)
