Aha!

Now I wonder how those got there?!


Hah!  Thanks for sharing.  Very satisfying to actually make a *correct*
prediction about setuptools' behavior :)

This seems to be Apple's doing.  AFAICT, 10.12 is shipping with this
Extras.pth file in /Library/Python/2.7; it's something new.  And,
unfortunately, due to https://bugs.python.org/issue4865, the
site-packages directory for the system Python 2.7 is included in
sys.path along with the non-system framework Python site-packages.

Hrm.  I guess everyone I knew on the beta was using homebrew python :(.

I'm surprised that Apple is putting stuff in /Library.  I don't have a
Sierra box handy - /Library isn't SIP-protected now, is it?

This seems wrong; someone should file a radar (and probably share
on http://www.openradar.me <http://www.openradar.me/> for further
discussion).

Did someone file a radar for this? Otherwise I can do so.

Not me. If I understand correctly, Glyph -- who undoubtedly understand the situation better than I do -- still thinks that there's no actual bug here, since we shouldn't be using the framework build this way, but I'm not sure I understand/agree...

I can affirm that Extras.pth is now in /Library/Python/2.7 instead of in
a system location. This sucks as bits of the system install now infect
other installs of Python 2.7. One more reason to stop using 2.7 I guess ;-)
