ImportError: No module named interface

After installing dedupe on linux ubuntu and following the developer setup guide (with python 2.7), I get

import dedupe
>> File "<stdin>", line 1, in <module>
  File "dedupe/__init__.py", line 16, in <module>
    from api import StaticDedupe, Dedupe
  File "dedupe/api.py", line 26, in <module>
    import dedupe.training as training
  File "dedupe/training.py", line 7, in <module>
    import blocking
  File "dedupe/blocking.py", line 9, in <module>
    from zope.index.text.textindex import TextIndex
  File "/usr/local/lib/python2.7/dist-packages/zope/index/text/__init__.py", line 1, in <module>
    from zope.index.text.textindex import TextIndex
  File "/usr/local/lib/python2.7/dist-packages/zope/index/text/textindex.py", line 19, in <module>
    from zope.interface import implementer
ImportError: No module named interface

Any clue ?

Resolved:

pip install --upgrade pip pip install --upgrade zope.interface

I’m getting it too with it installed:

zope.event==4.0.3
zope.index==4.1.0
zope.interface==4.0.5
zope.schema==4.4.2
