When creating a custom Command (or sub-classing one) we cannot initialize in "initialize_options()" the "force" option to 1, because Command.__init__ resets it to None after the call to self.initialize_options().

Could you tell how you found the problem, i.e. what are you trying to do?

(from the PR11526)
In this build_py subclass I initialize force to 1, but when reaching byte_compile() we find out it was reset to None.

from setuptools.command.build_py import build_py as _build_py

class build_py(_build_py):
    def initialize_options(self):
        _build_py.initialize_options(self)
        self.force = 1
        self.compile = 1

    def byte_compile(self, files):
        # self.compile == 1
        # self.force == None
        _build_py.byte_compile(self, files)
        # do stuff...

Distutils is now deprecated (see PEP 632) and all tagged issues are being closed. From now until removal, only release blocking issues will be considered for distutils.

If this issue does not relate to distutils, please remove the component and reopen it. If you believe it still requires a fix, most likely the issue should be re-reported at https://github.com/pypa/setuptools
