OS X AppEngine - ImportError: Brak modułu o nazwie _sqlite3

AKTUALIZACJA: To jest problem, który mam z 1.8.0 App Engine SDK przy nowej instalacji OS X 10.8.3.

Po pierwsze - jest kilka pytań na temat SO o podobnym tytule. Sprawdziłem je i nie wierzę, że odpowiedzą na moje pytanie. Najczęściej zalecają pobranie libsqlite3-dev i przebudowanie pythona, aby uzyskać _sqlite3.so, ale to już powinno być:

$ find / -name _sqlite3.so
Password:
...
/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_sqlite3.so
/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/_sqlite3.so
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_sqlite3.so

Rzeczywisty kod powodujący próbę załadowania tego modułu przez SDK aparatu aplikacji:


remaining = TaskSetElement.all().filter('taskSet', ts_key).filter('complete', False).count()

Oto ślad stosu SDK:


  File "~/dev/myApp/myApp/task.py", line 90, in completeTaskSetElement
    remaining = TaskSetElement.all().filter('taskSet', ts_key).filter('complete', False).count()
  File "~/dev/GAE/google_appengine/google/appengine/ext/db/__init__.py", line 2133, in count
    result = raw_query.Count(limit=limit, **kwargs)

    batch = self.GetBatcher(config=config).next()

    return self.next_batch(self.AT_LEAST_ONE)

    klass = self.find_class(module, name)

    __import__(module)

Mam kilka kodów do przechowywania danych przed tą linią, która działa poprawnie. Mam ten sam problem z uruchomieniem dev_appserver.py bezpośrednio z wiersza poleceń lub z eclipse za pomocą pydev.

Z linii poleceń wszystko wygląda dobrze:

$ python

>>>

Ten fragment kodu (działający w zestawie SDK aparatu aplikacji) usuwa kod magazynu danych aparatu aplikacji z równania:


...
logging.info("Python Version: %s" % sys.version)
logging.info(filter(lambda p: 'lib-dynload' in p, sys.path))

import sqlite3
...

Wyprowadza to:

Jakieś pomysły na problem? Dzięki,
