я бегуДжанго 1,8 а такжеPython 3.4 наUbuntu 14.04 LTS, Совсем недавно мое приложение Django сообщало, чтоGEOS нетGEOS установлен иlibgeos_c.so где это должно быть (/ USR / Библиотека /). Мой код кажется в порядке. Это источник образа докера, который все еще работает. Похоже, это указывает на проблему с ОС / несовместимостью. Любая помощь приветствуется.

django.core.exceptions.ImproperlyConfigured: GEOS is required and has not been detected. Are you sure it is installed? See also https://docs.djangoproject.com/en/1.8/ref/contrib/gis/install/geolibs/

Я пытался переустановитьlibgdal-DEV, Все соответствующие пакеты (GDAL, GEOS и т. Д.) Обновлены.

Я попытался вернуться обратно через код Python. это терпит неудачу вdjanjo / вно / ГИС / GEOS / __ init__.py на следующем. Поскольку для HAS_GEOS установлено значение false, он сообщает, что GEOS отсутствует.

try:
    from .libgeos import geos_version, geos_version_info  # NOQA: flake8 detects only the last __all__
    HAS_GEOS = True
    __all__ += ['geos_version', 'geos_version_info']
except ImportError:
    HAS_GEOS = False

Я подозреваю, что недавнее обновление / исправление ОС сломало GEOS или GDAL. Кажется, коренная причина в том, чтоctypes, но я не вижу, что это может быть.

Следующее может быть полезно.
