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

The idea behind this idea is so I could load the sgp4_pure_python package and then load skyfield
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 force sgp4_pure_python to be loaded before skyfield as all is async, or
2. Its possible micropip does not pay attention to the provides tag in sgp4_pure_python package, or
3. Maybe I can fool it by somehow setting the deps option in micropip.
   • Invoked like this: micropip.install("pkg", deps=False)
   • Is there a way to signal deps 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)
