apache mod_wsgi错误与django在virtualenv中(apache mod_wsgi error with django in virtualenv)

 我似乎无法找到一个好的答案。 在将其作为WSGIDaemon运行时，谁需要拥有virtualenv？ 我假设我的操作系统（Ubuntu 16）www-data，但我想确定。 根据这篇文章的答案，尝试一些新的东西让这件事工作...... 
 
 django apache配置与WSGIDaemonProcess无法正常工作 
 
 django项目，virtualenv文件夹或两者都需要由apache组拥有吗？ 在没有指定端口的情况下，需要为django项目提供什么样的所有权？ 为什么我会得到以下内容？ 
 
 根本问题： 
 
 Call to 'site.addsitedir()' failed for '(null)'
 
 当我启动Apache时，我收到此错误。 我遵循了几个不同的指南，包括： http ： //modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html和https://docs.djangoproject.com/en/1.10/howto/部署/ wsgi / modwsgi /但没有成功。 
 
 我的虚拟环境路径是/usr/local/virtualenvs/servicesite 
 
 我的django项目路径是/home/addohm/projects/rtservice/servicesite 这是manage.py所在的位置 ，它将/home/addohm/projects/rtservice/servicesite/servicesite留作我的wsgi.py的位置。 
 
 wsgi.py： 
 
SERVICESITE = ['/usr/local/virtualenvs/servicesite/lib/python3.5/site-packages']

import os
import sys
import site

prev_sys_path = list(sys.path)

for directory in SERVICESITE
        site.addsitedir(directory)

new_sys_path = []
for item in list(sys.path):
        if item not in prev_sys_path:
                new_sys_path.append(item)
                sys.path.remove(item)
sys.path[:0] = new_sys_path

"""  **Doesn't seem to work, throwing error in apache logs**
site.addsitedir('/usr/local/virtualenvs/servicesite/lib/python3.5/site-packages')
"""

from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "servicesite.settings")
application = get_wsgi_application()
DJANGO_PATH =  os.path.join(os.path.abspath(os.path.dirname(__file__)), '..')
sys.path.append(DJANGO_PATH)

I can't seem to find a good answer to this. Who needs to own the virtualenv when running it as a WSGIDaemon? I assume on my OS (Ubuntu 16) www-data, but I want to be sure. Trying some new things to get this thing working based off of the answer from this post...
 
django apache configuration with WSGIDaemonProcess not working
 
Does the django project, the virtualenv folder, or both need to be owned by the apache group? What ownerships need to be in place to serve a django project without specifying a port? Why do I get the following? 
 
The root problem:
 
 Call to 'site.addsitedir()' failed for '(null)'
 
When I start apache, I get this error. I've followed several different guides, including: http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html and https://docs.djangoproject.com/en/1.10/howto/deployment/wsgi/modwsgi/ but have had zero success.
 
My virtual environment path is /usr/local/virtualenvs/servicesite
 
My django project path is /home/addohm/projects/rtservice/servicesite this is where manage.py resides, which leaves /home/addohm/projects/rtservice/servicesite/servicesite as the location of my wsgi.py.
 
wsgi.py:
 
SERVICESITE = ['/usr/local/virtualenvs/servicesite/lib/python3.5/site-packages']

import os
import sys
import site

prev_sys_path = list(sys.path)

for directory in SERVICESITE
        site.addsitedir(directory)

new_sys_path = []
for item in list(sys.path):
        if item not in prev_sys_path:
                new_sys_path.append(item)
                sys.path.remove(item)
sys.path[:0] = new_sys_path

"""  **Doesn't seem to work, throwing error in apache logs**
site.addsitedir('/usr/local/virtualenvs/servicesite/lib/python3.5/site-packages')
"""

from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "servicesite.settings")
application = get_wsgi_application()
DJANGO_PATH =  os.path.join(os.path.abspath(os.path.dirname(__file__)), '..')
