我安装了apache和mod_wsgi模块来部署django应用程序。
我的机器中有anaconda作为python发行版，所以我这样安装了mod_wsg：
$ ./configure --with-apxs=/usr/local/apache2/bin/apxs \
--with-python=ANACONDA_PATH/bin/python
$ make
$ make install
所以，我向mod_wsgi表示要使用anaconda的蟒蛇。
然后，我将模块mod_wsgi添加到apache2的httpd.conf。
我将此添加到000-default.conf
Alias /static PATH_TO_MY_PROJECT/MYPROJECT/static
<Directory PATH_TO_MY_PROJECT/MYPROJECT/static>
Require all granted
</Directory>
<Directory PATH_TO_MY_PROJECT/MYPROJECT/MYPROJECT/>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
WSGIScriptAlias / PATH_TO_MY_PROJECT/MYPROJECT/MYPROJECT/wsgi.py
我重启了apache，但是当我尝试在浏览器上运行localhost时，我收到了这个错误日志。

这里的问题是，mod_wsgi指向/usr/lib/python2.7/dist-packages，我需要它指向我在mod_wsgi安装中指定的anaconda的sites-packages。
有任何帮助吗？我会愉快地回答额外的问题。
