我加入站点包，在这里我一直Django的子目录（/Library/python/2.7/site-packages），以WSGIDaemonProcess的位置，解决了这个问题：

I solved the problem by adding location of site-packages, where I have kept django subdirectory (/Library/python/2.7/site-packages) to WSGIDaemonProcess:

WSGIDaemonProcess www.example.com processes=2 threads=15 display-name=%{GROUP} 
    python-path=/Library/python/2.7/site-packages

如果您使用的是的httpd.conf 嵌入式服务器模式中使用：

If you are using embedded server mode use in httpd.conf:

WSGIPythonPath /Library/python/2.7/site-packages
