GeoDjango w systemie Windows: Spróbuj ustawić GDAL_LIBRARY_PATH w ustawieniach

Question

Robiłem to kilkanaście razy wcześniej, ale coś nie działa ten czas ..

Po docs:

https://docs.djangoproject.com/en/1.11/ref/contrib/gis/install/#windows

Próbuję skonfigurować GeoDjango na komputerze z systemem Windows (ten jest wirtualnym systemem Windows 10 skonfigurowanym na paperspace.com). Wygląda na to, że występuje problem z ustawieniami PATH, ale nie wiem, co to jest. Uruchomiłem polecenia podświetlone w instrukcjach. Sprawdziłem zmienne PATH i wszystko wydaje się w porządku. Próbowałem skierować ich zarówno do 32-bitowych, jak i 64-bitowych wersji OSGeo4Win. Niezależnie od tego, za każdym razem otrzymuję następujący wynik:

Czy ktoś ma jakieś pomysły?

AKTUALIZACJA: Poszedłem do sklepu i kupiłem nowy laptop, a ja wciąż mam ten sam problem. Czy może to być problem z wersjami niektórych zależności GeoDjango? Nie mam pojęcia, co robić, ale jest to dla mnie nagła sytuacja.

Answer 1

Problem zakończył się jako version mismatch between Django and GDAL. Django nie szukał prawidłowej nazwy pliku (gdal202.dll w moim przypadku).

Fixing to wymagane mi dodać str('gdal202') do następnego pliku w wierszu 26:

(Python Root)\Lib\site-packages\django\contrib\gis\gdal\libgdal.py

Jeśli problem wystąpi ponownie, można przejrzeć katalogu OSGeo4W\bin, aby dowiedzieć się, które gdalxxx.dll to jest, że potrzeby Django szukać.

Answer 2

Dodawanie

GDAL_LIBRARY_PATH = r'C:\OSGeo4W64\bin\gdal202' 

ustawień django pracował dla mnie
