My bad: 4.0.0 was the first version *without* py2.7 support, so this was
supposed to be:
install_requires=(
"importlib_resources<4.0.0;python_version<'3.0'",
"importlib_resources;python_version>='3.0' and python_version<'3.7'",
),
Somehow this does not seem to make a difference. Maybe the last wheel
for 2.7 being the last supported version was making my bogus dependency
accidentally work (for as far as importlib_resources version itself is
concerned, so ignoring the zipp error).
