Я новичок в разработке вообще и django. В настоящее время у меня есть ошибка ниже, когда я использую команду 'python manage.py runserver' после изменения Default Database Engine при установке на
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'agricom',
'USER': 'postgres',
'HOST': 'localhost',
'PASSWORD': 'pass',
'PORT': '5432',
}
}
Я получаю ошибку ниже;
не может импортировать имя 'GDALRaster' из 'django.contrib.gis.gdal'
