pyhash install failes with compilation error in fnv.h #61

There are other issues posted related to installing but this case does not seem to covered.

I am trying to install pyhash with pip. On Ubuntu 20.04.3 with Python 3.8 I was able to install after changing setuptools to 57.5.0 (python -m pip install 'setuptools~=57.5.0')

But on Windows 10 and Python 3.10 I get a compilation error. There are multiple questions here on SO about installing pyhash; based on this answer I made the following changes:

python -m pip install 'setuptools~=57.5.0' $env:PYTHON_HOME='C:\Users\I063510\AppData\Local\Programs\Python\Python310' pip install wheel Now I get warning and errors as follows :

C:\Users\USERID\AppData\Local\Programs\Python\Python310\lib\site-packages\setuptools\lib2to3_ex.py:36: SetuptoolsDeprecationWarning: 2to3 support is deprecated. If the project still requires Python 2 support, please migrate to a single-codebase solution or employ an independent conversion process.

I don't care about Python 2 so this in not an issue, but I don't know how to disable it.

This error aborts the installation:

This is no longer critical for me as I found another fast and stable hash
