The installation instructions as written currently fail for recent-ish environments. The distutils module which the setup.py script relies on was removed from the standard library in Python 3.12.
While long-term the updating of setup.py to account for the distutils removal would likely be ideal, a workaround is to explicitly specify Python version 3.11 (or earlier), which still has distutils availible. -- e.g. replace the current first line of installation with something like conda create -n ANARCI -c conda-forge biopython python=3.11 -y to make an environment with a compatible version of python.
(Even then, installation outputs a warning message with a link to https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html -- the program still works, though.)
