Just in case some developers are facing this problem on Ubuntu, I solved it just installing libgeos-lib
以防万一一些开发人员在 Ubuntu 上遇到这个问题，我只安装了 libgeos-lib 就解决了
sudo apt-get install libgeos-dev
sudo apt-get install libgeos-dev

I had the same problem with postgis via MacPorts in combination with Django, although I could execute select postgis_full_version();without issues. This answer helped me: http://pragmaticstartup.wordpress.com/2012/09/30/django-core-exceptions-improperlyconfigured-could-not-import-user-defined-geometry_backend-geos/
我通过 MacPorts 与 Django 结合使用 postgis 遇到了同样的问题，尽管我可以select postgis_full_version();毫无问题地执行。这个答案帮助了我：http: //pragmaticstartup.wordpress.com/2012/09/30/django-core-exceptions-improperlyconfigured-could-not-import-user-defined-geometry_backend-geos/
The solution for me was to add
我的解决方案是添加
export DYLD_FALLBACK_LIBRARY_PATH=$DYLD_FALLBACK_LIBRARY_PATH:/opt/local/lib/
to ~/.profile. (Don't forget to source it before trying again)
到~/.profile。（在再次尝试之前不要忘记获取它的来源）

I found that I'd originally installed geos through pip.
我发现我最初是通过 pip 安装 geos 的。
Once I downloaded the new GEOS library from: http://www.kyngchaos.com/software/frameworks#geos
一旦我从以下位置下载了新的 GEOS 库：http: //www.kyngchaos.com/software/frameworks#geos
Then installed it.
然后安装了它。
Last, I added to my path (~/.bash_profile):
最后，我添加到我的路径 (~/.bash_profile)：
export PATH=/Library/Frameworks/GEOS.framework/Versions/3/unix/lib/:$PATH
It worked fine.
它工作得很好。

Have you installed the geoslibrary?
您是否安装了geos库？
It's included in the instructions for installing GeoDjango with macports.
