"django.core.exceptions.ImproperlyConfigured": GEOS gerekli ve algılanmadı. " GEOS

Question

yüklü rağmenDjango 1.8 ve Ubuntu 14.04 LTS üzerinde Python 3.4 koşuyorum. Yakın zamanda, Django uygulamam GEOS'un mevcut olmadığını bildiriyor. GEOS yüklendi ve libgeos_c.so olması gereken yerde (/usr/lib/). Kodum iyi görünüyor. Hala çalışan bir docker görüntüsünün kaynağıdır. Bu bir os/uyumsuzluk sorunu olduğunu gösteriyor. Herhangi bir yardım çok takdir edilecektir.

olduğunu. İlgili tüm paketler (GDAL, GEOS vb.) Günceldir.

Python koduna geri dönmeyi denedim. djanjo/contrib/gis/geos/__ init__.py'da aşağıdaki hatalardan dolayı başarısız olur. HAS_GEOS yanlış olarak ayarlandığında, GEOS'un mevcut olmadığını bildirir.

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 

Yeni bir işletim sistemi yükseltmesi/düzeltme ekinin GEOS veya GDAL bozuk olduğundan şüpheleniyorum. Kök nedeni, ktypes ile ilgili bir şey gibi görünüyor, ancak ne olabileceğini göremiyorum.

Aşağıdakiler yararlı olabilir.

Answer 1

Benimle aynı olmayan bir python projesinde de aynı problemi yaşadım. Bu benim de karşılaşılan çizgidir ve hangi burada götürdü: Ubunut mevcut sanal ortamlar ile uyumlu olmayan bir Python 3.4 güncellemesini itti gibi

ImportError: /usr/lib/python3.4/lib-dynload/_ctypes.cpython-34m-x86_64-linux-gnu.so: undefined symbol: _PyTraceback_Add 

görünüyor. Ben sanalenv yeniden oluşturarak sorunu çözebilir. Bu andan için kullanışsız olduğu nereden basitçe sistemin bir ile VIRTUALENV en piton değiştirilir:

cd my-virtualenv 
cp /usr/bin/python3.4 bin/python3.4 

bunu yapmak için çok aklı başında şey olup olmadığını söyleyemem, ama çalışmak görünüyor benim vaka. Bu gerçek dışı Sembolik bağ dosya, çünkü

Answer 2

Sen, yerine

cp /usr/bin/python3 /path/to/my-virtualenv/bin/python3 

yapmalıdır.
