[Issue]: pip install qf-lib yields legacy-install-failure

[Olivianita]

Summary

When doing
pip install qf-lib

I get Error: legacy-install-failure. Encountered error while trying to install package. numpy

I got:

python version: 3.10.9

These are the things I've installed prior to getting to this point:
Anaconda

conda install -c conda-forge multitasking
conda upgrade pip
conda install -c conda-forge yfinance

installed html5lib using Anaconda Navigator

pip install --upgrade clyent
pip install --upgrade nbformat
pip install --upgrade requests

Please let me know how to get passed this error, or whether you need further information from me to help debug this QF-LIB installation error.

Thanks

Hi,
Currently qf-lib does not support python >= 3.10. The implementation is planned, but not in the next two business quarters.
As for now we support:

• python 3.7 - 3.9
• numpy>=1.19.3,<1.21.0
• blpapi>=3.16.2,<3.18.0
