Django, PostgreSQL и SQLAlchemy

Question

после запуска чистых баз проекта на эти пакеты (в основном мой requirements.txt):

Django>=1.7, <1.8 
psycopg2 
aldjemy 

Мои python manage.py migrate вызывать ошибки:

не имеет значения, какую базу данных Я использую в своей конфигурации postgresql или sqlite, поэтому я понимаю, что SQLAlchemy вызывает расширение. Но я не могу понять, где проблема. Вы можете помочь?

Также я использую Python3.4, так как вы можете видеть из журналов.

Установка непосредственно с repository помогает!
