[I tried to comment via the gmane newsgroup version of the lists and my
messages never appeared so I hope this works…]
Just to be clear, I am indeed using the framework pip, which is part of why
this is so confusing. In the past, as far as I know, it’s never tried to have
anything to do with /System. Again, I don’t know if it’s something about macOS
10.12 Sierra, or my particular setup that is the problem. Also, to be clear,
there are no PYTHON* or other environment variables that would affect the
python path. Here is a failing session…
(Aside: I understand that "pyobjc-framework-Message” is actually a bad example:
it is the only package that even —-ignore-installed actually fails on, because
it has the "--single-version-externally-managed” problem which is a different
kettle of fish. But I think the above error message is the same as the one that
I would get for any of the other packages in question. Note that pip2 install
works fine for packages other than those in my original list.)
