我一直在尝试在 ubuntu 14.04 上部署我的 Django 应用程序，并安装了以下软件包：
django 1.4.15
apache 2.4
python 2.7
mod_wsgi 3.4 (there is one compiled as mod_wsig.so-2.7 which is the one I use)
在我的 apache 配置中，我有以下字段：
# Modules
LoadModule mpm_worker_module /usr/lib/apache2/modules/mod_mpm_worker.so
LoadModule mime_module /usr/lib/apache2/modules/mod_mime.so
LoadModule alias_module /usr/lib/apache2/modules/mod_alias.so
LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so-2.7
LoadModule setenvif_module /usr/lib/apache2/modules/mod_setenvif.so
LoadModule authn_core_module /usr/lib/apache2/modules/mod_authn_core.so
LoadModule authz_core_module /usr/lib/apache2/modules/mod_authz_core.so
...
<Directory />
Options FollowSymLinks
AllowOverride None
AuthType none
Require all granted
</Directory>
...
# And finally the app config.
WSGIPythonHome /home/web/.virtualenvs/web
WSGIPythonPath /PATH/TO/MYSITE:/home/web/.virtualenvs/web/lib/python2.7/site-packages
WSGIScriptAlias / "/PATH/TO/wsgi.py"
在我尝试导入系统中的一个本地模块之前，一切似乎都很好。我的意思是，wsgi.py 脚本运行没有问题，然后 django settings.py 开始运行，在设置中我有这个代码：
from MYSITE.environments.prod_settings import *
环境是一个模块，它有自己的__init__.py文件和所有。但是当它到达那条线时，它无法导入。
另一部分是网站在我运行时运行完美，./manage.py runserver并且 sys.path 中的信息是一样的！
我只是不知道为什么 apache wsgi 不会让我导入那个 python 模块。
这是最新的日志：

在模块错误之后，日志错误通常是关于数据库连接的问题。发生这种情况是因为在 wizzytest2 模块中我有设置覆盖，所以这是预期的。

刚刚也添加了 python 路径，这样更容易调试。我还修复了 newrelic 问题，但这对是否找到设置文件wizzytest2没有任何影响。
