[issue46579] Compiling from source prints «ModuleNotFoundError: No module named 'binascii'»

Christian Heimes  added the comment:

CPython's build system does not depend on setuptools.

The problem is that setuptools 60.0 introduced a .pth file and _distutils_hack 
to inject itself into Python import system. Under some circumstances Python's 
build system is affected by the hack and breaks.

The problem is, that Python’s install target depends on the system-wide 
setuptools, if there is system-wide setuptools.  If there is no system-wide 
installed setuptools, apparently the installation works flawlessly.

The solution is to tweak the source code of Python, not to depend on 
(system-wide installed) Python code outside of Python’s tarball.

You are affected by setuptools bug 
https://github.com/pypa/setuptools/issues/3007 . The setuptools issues has a 
workaround. The next version of setuptools will come with a fix.

When I compiled python 3.10 using python 3.8 one or two months ago, there was 
no such problem.

Compiling python from source code, shall use the bundled distutils, not the 
installed one.

My Linux From Scratch system appears not to have module binascii:

$ locate binascii
/usr/local/lib/python3.10/lib-dynload/binascii.cpython-310-x86_64-linux-gnu.so
/usr/local/lib/python3.10/test/__pycache__/test_binascii.cpython-310.opt-1.pyc
