Ich bin neu in Django. Ich habe Django mit easy_install (auf einem Mac) und dem PyDev Django-Plugin für Eclipse installiert. Ich habe die Standardverfahren befolgt, um ein neues PyDev Django-Projekt zu erstellen. Wenn ich versuche, das Projekt als PyDev: Django auszuführen, wird folgende Fehlermeldung angezeigt.

Validating models...

RuntimeError: maximum recursion depth exceeded

Ich habe auch versucht, die folgende Zeile in manage.py hinzuzufügen, aber es hat keinen Sinn.

sys.setrecursionlimit(2000)

Hier ist die teilweise Stapelspur.
