PointField() funktioniert nicht korrekt in GeoDjango

Question

Ich habe GDAL (mit homebrew) und SQLite installiert. Ich möchte einen Lehrer mit einem PointField() erstellen, der lange und lat-Werte speichert, um ihren Standort zu kennen. Später plane ich die Möglichkeit, wie nach der Entfernung mit etwas zu suchen, über das Hinzufügen von:

Teacher.objects.filter(location__distance_lte=(your_location,D(m=distance))).distance(your_location).order_by('distance') 

models.py

from django.db import models 
from django.contrib.gis.db import models as gis_models 
from django.contrib.auth.models import User 

class Teacher(models.Model): 
    user = models.ForeignKey(User, unique=True) 
    location = gis_models.PointField() 
    availability = models.BooleanField(default=False) 

Allerdings, wenn ich den Server laufen, ich die folgende Fehlermeldung erhalten:

Answer 1

Dies ist ein bekanntes Problem, das behoben wurde und in Django v1.11.5 ausgerollt wird.

Wenn Sie nicht für 1.11.5 warten können oder wollen nicht auf dem dev Zweig laufen, Sie zu einer früheren Version von GEOS gehen können:

brew switch geos 3.6.1
