"setup.py install" skips zope/interface/common/

[Jean-Paul Calderone]

After installing the 3.6.1 release from PyPI, the zope.interface.common package is not available:

  exarkun@boson:~/Downloads$ tar xzf zope.interface-3.6.1.tar.gz
  exarkun@boson:~/Downloads$ cd zope.interface-3.6.1/
  exarkun@boson:~/Downloads/zope.interface-3.6.1$ python setup.py install --quiet --prefix /tmp/ZOPE-TEST
  /usr/lib/python2.6/distutils/dist.py:266: UserWarning: Unknown distribution option: 'test_suite'
  ....
  exarkun@boson:~/Downloads/zope.interface-3.6.1$ PYTHONPATH=/tmp/ZOPE-TEST/ python -c 'from zope.interface import common'
  Traceback (most recent call last):
    File "<string>", line 1, in <module>
  ImportError: cannot import name common
  exarkun@boson:~/Downloads/zope.interface-3.6.1$

Hmm, this seems to be true only when installing without setuptools:

Okay. Why is this marked as Incomplete?

[Glyph Lefkowitz (glyph)]

I just heard about a case of this happening on Ubuntu 12.10. I suspect it's a bug in setuptools or distutils or ubuntu's patching of same, not zope.interface; can someone comment on what mechanism ZI uses to include the 'common' package? I don't see it in setup.cfg, or a manifest file... I am guessing there's some setuptools magic which is supposed to make it get included.

[Glyph Lefkowitz (glyph)]

Also of note; setuptools *was* installed on the system where this happened. It was zope.interface 4.0.3 in this case.
