Not installable on Python 3.11.2

Hello

Thank you for developping this fantastic library. I'd love to use it, but running Python 3.11.2. Will it be available for that version in the near future?

However, this seems to be an issue with numba:

  Using cached numba-0.56.4.tar.gz (2.4 MB)

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

Thank you

Hello,

1. It seems that you can remove jit functions from the source code
2. Then install numpy from source code

Hi @RandomBloke85,

This is because PyBroker depends on Numba, and Numba does not yet support Python 3.11. However, Numba support is coming very soon, and there is a release candidate available for 3.11 (numba/numba#8841). In the meantime, you will need to use Python 3.9 or 3.10.

Hi @RandomBloke85,

Good news! PyBroker v1.1.9 now supports Python 3.11.

Hi @edtechre

Thanks for letting me know. Just installed without flaws so far. Will have a look into it. Thx for developping such a great tool!

Thanks @RandomBloke85!

I just pushed a change today that affects how market values of short positions are calculated. Be sure to upgrade to the latest version:
pip install --upgrade lib-pybroker
