Обновление GeoDjango приложение к django1.9

Question

Я пытаюсь обновить мой Джанго проект от django1.8.8 к django1.9.2 Сейчас я сталкиваюсь с проблемой при выполнении моих тестов с django1.9.2:

python manage.py test 

Это дает мне следующую ошибку

django.db.utils.InternalError: PostGIS is already installed in schema 'public', uninstall it first 

В django1.8 все работает должным образом. Есть изменения в django1.9 и postgis Я не знаю?

Answer 1

Я мог бы решить эту проблему путем жесткого сброса данных.

Answer 2

Возможно, это связано с postgis. Убедитесь, что postgres имеет расширение postgis.
