I recently added a yandex-maps application to my django project, fulfilling all the installation instructions. However, when I try to open the page with {% load yandex_maps_tags %} tag, I get an error:
TemplateSyntaxError: 'yandex_maps_tags' is not a valid tag library: ImportError raised loading yandex_maps.templatetags.yandex_maps_tags: Could not find the GEOS library (tried "geos_c", "GEOS"). Try setting GEOS_LIBRARY_PATH in your settings.
I didn't install a custom version of GEOS library, I didn't install it at all. However, when I click on the import line in yandex-maps library and press ⌘-B, I'm taken to GEOS's library __init__.py file, which is located at /Library/Python/2.7/site-packages/django/contrib/gis/geos/__init__.py. I don't know what is supposed to be a standard path for this library, but it looks like it to me.
I'm completely lost with this error. What can I do about it?
In order to use django.contrib.gis.geos you need first install GEOS library. Here are the instructions.
If you'll still have problems, see Can’t find GEOS library django docs.
Hope that helps.
