Python GEOS ImportError

我收到此错误：

ImportError: Could not find the GEOS library (tried ""geos_c"", ""libgeos_c-1"").  
Try setting GEOS_LIBRARY_PATH in your settings

当我跑步时：

from django.contrib.gis.geos import *
pnt=GEOSGeometry('POINT(23 5)')
print(pnt)

我加入GEOS_LIBRARY_PATH = 'C:/Python34/Lib/site-packages/osgeo/geos_c.dll'
了C:\Python34\Lib\site-packages\django\conf\project_template\project_name\settings.py

但我仍然遇到相同的错误。如何解决呢？
