Currently, we define the following macros:

%python3_sitelib %(%{__python3} -Ic "from distutils.sysconfig import get_python_lib; print(get_python_lib())")
%python3_sitearch %(%{__python3} -Ic "from distutils.sysconfig import get_python_lib; print(get_python_lib(1))")

%python_sitelib %(%{__python} -Esc "from distutils.sysconfig import get_python_lib; print(get_python_lib())")
%python_sitearch %(%{__python} -Esc "from distutils.sysconfig import get_python_lib; print(get_python_lib(1))")

But distutils is deprecated in Python 3.10: https://www.python.org/dev/peps/pep-0632/

We need to figure out how to get this data from somewhere else.

I've checked and sysconfig does not have get_python_lib(), but it has get_path(). This is a code that we can use:

>>> from sysconfig import get_path
>>> get_path('platlib') 
'/usr/lib64/python3.9/site-packages'
>>> get_path('purelib')
'/usr/lib/python3.9/site-packages'


It seems to work across variety of our Pythons:

$ for PYTHON in python{2.7,3.{5..10}} pypy2 pypy3; do echo $PYTHON; $PYTHON -c 'from __future__ import print_function; from distutils.sysconfig import get_python_lib; from sysconfig import get_path; print(get_path("platlib"), get_python_lib(1), get_path("platlib")==get_python_lib(1)); print(get_path("purelib"), get_python_lib(), get_path("purelib")==get_python_lib())'; echo; done
