(1) Poliastro install fails on Python 3.11.2 ?

python --version
Python 3.11.2
I do not have an earlier version of Python.

I just want to run some Poliastro examples to understand the scope of time commitment to get the Poliastro to run.
I plan on development thru VSCode ; I have a windows10 machine...

Yes, I realize the Poliastro install instruction;
"poliastro is supported on Linux, macOS and Windows on Python 3.8 to 3.10". Is there a timeframe to test Poliastro for later versions of Python?

🐞 Problem

python -m pip install https://github.com/poliastro/poliastro/archive/main.zip
RuntimeError: Cannot install on Python version 3.11.2; only versions >=3.7,<3.11 are supported.

note: This error originates from a subprocess, and is likely not a problem with pip.

(2) Some dependents install fail
Last time I fooled with Poliastro, I never got past getting the dependent packages; 2016, so I gave up. I am hoping this time is different. Thus far only numba fails to install (due to python version, I believe). Perhaps in a future documentation version someone can provide new users with "better" installation guidance. To me the lesson-to-be-learned is to reduce/eliminate "package" dependencies as much as possible.

2a) pip install astropy : fails (then passes after VS download)
To me, following the pip error instructions, it is not clear which C++ tools to install from MicroSoft.
I do not want the full baggage of Visual Studio (VS) as suggested in the pip error message. But after I loaded
the VS component I believed I needed, I think the astropy install passed.

2b) pip install jplephem : passes
Also installs NumPy , nice

2c) pip install matplotlib : passes

2d) pip install numba : fails
Error message; not support Python version >3.11

2e) pip install plotly (took ~4 minutes to install) : passes

2f) pip install SciPy : passes

Thank you for your help.

Situation is the same on Ubuntu Linux too, but the current main on GitHub does work, so one can pip install git+https://github.com/poliastro/poliastro.git
