问题
I'm trying to get my cookiecutter-django app running under Apache with mod_wsgi installed via pip.
python3 manager.py runserver works.
But after running it in Apache, I got an error saying Module config not found. So I pip install config. (It is not installed on my development system.)
That put a config.py file in my /usr/local/pulseenv/lib/python3.5/site-packages.
That file had various syntax errors which I fixed. The errors were due to changes between python 2.7 and 3.5 as far as I can tell.
But now I get this error and I'm stuck where to go from here:
ImportError: No module named 'config.settings'; 'config' is not a package
I don't see any clues in the error.log on how to further trace the error. So what is this module? Why do I need it? And how to figure out my problem is?
EDIT:
Here's my vhost file (/etc/apache2/sites-available/000-default.conf):

EDIT 2:
I do have a config directory:
ubuntu@ip-172-31-84-213:~$ cd /var/www/pulsemanager/config/
ubuntu@ip-172-31-84-213:/var/www/pulsemanager/config$ ls
__init__.py __pycache__ settings urls.py wsgi.py
ubuntu@ip-172-31-84-213:/var/www/pulsemanager/config$ cd settings
ubuntu@ip-172-31-84-213:/var/www/pulsemanager/config/settings$ ls
base.py __init__.py local.py production.py __pycache__ test.py
ubuntu@ip-172-31-84-213:/var/www/pulsemanager/config/settings$
And here's my wsgi.py. Seems like DJANGO_SETTINGS_MODULE should be defaulting to config.settings.production (/var/pulsemanager/config/settings/production.py):
"""
WSGI config for pulsemanager project.
"""
import os
import sys
from django.core.wsgi import get_wsgi_application
# This allows easy placement of apps within the interior
# pulsemanager directory.
app_path = os.path.dirname(os.path.abspath(__file__)).replace('/config', '')
sys.path.append(os.path.join(app_path, 'pulsemanager'))
if os.environ.get('DJANGO_SETTINGS_MODULE') == 'config.settings.production':
from raven.contrib.django.raven_compat.middleware.wsgi import Sentry
# We defer to a DJANGO_SETTINGS_MODULE already in the environment. This breaks
# if running multiple sites in the same mod_wsgi process. To fix this, use
# mod_wsgi daemon mode with each site in its own daemon process, or use
# os.environ["DJANGO_SETTINGS_MODULE"] = "config.settings.production"
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production")
# This application object is used by any WSGI server configured to use this
# file. This includes Django's development server, if the WSGI_APPLICATION
# setting points here.
application = get_wsgi_application()
if os.environ.get('DJANGO_SETTINGS_MODULE') == 'config.settings.production':
application = Sentry(application)
# Apply WSGI middleware here.
# from helloworld.wsgi import HelloWorldApplication
# application = HelloWorldApplication(application)
EDIT 3:
I removed the config package. I'm pretty sure that was a red herring. I see several references to 'config', e.g os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production") and app_path = os.path.dirname(os.path.abspath(__file__)).replace('/config', '') in wsgi.py. Is one of these things where my problem is?
I added export DJANGO_SETTINGS_MODULE=config.settings.production to config/__init__.py and even tried putting os.environ["DJANGO_SETTINGS_MODULE"] = "config.settings.production" near the top of wsgi.py.
I updated WSGIDaemonProcess to:
WSGIDaemonProcess pulsemanager python-home=/usr/local/pulseenv/ python-path=/var/www/pulsemanager/pulsemanager:/usr/local/pulseenv/lib/python3.5/site-packages
but I'm still getting:
ImportError: No module named 'config'

回答1:
Your DJANGO_SETTINGS_MODULE needs to specify a package or module that exists in the project root folder.
[pulsemanager]/
├── [config]/
│ ├── __init__.py
│ ├── settings.py
│ ├── urls.py
│ └── wsgi.py
└── manage.py
Using virtualenv
WSGIPythonPath /path/to/mysite.com:/path/to/your/venv/lib/python3.X/site-packages
Using mod_wsgi Daemon Mode
WSGIDaemonProcess pulsemanager python-path=/path/to/pulsemanager:/path/to/venv/lib/pytho\
n2.7/site-packages
WSGIProcessGroup pulsemanager
For multiple sites run in a single mod_wsgi process, all of them will use the settings of whichever one happens to run first. This can be solved by changing:
os.environ["DJANGO_SETTINGS_MODULE"] = "{{ project_name }}.settings.{{env}}"
Updated wsgi.py
import os
import sys
from django.core.wsgi import get_wsgi_application
sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "pulsemanager.settings.production")
if os.environ.get("DJANGO_SETTINGS_MODULE") == "pulsemanager.settings.production":
from raven.contrib.django.raven_compat.middleware.wsgi import Sentry
application = Sentry(get_wsgi_application())
else:
get_wsgi_application()

I once had a similar issue to the above:
$ py -3 bloody.py
Traceback (most recent call last):
File "bloody.py", line 1, in <module>
import requests
ModuleNotFoundError: No module named 'requests'
This occurred even though I had followed the instructions on the Cisco Devnet website, which suggested:
pip install requests
What I ended up running was:
py -2 -m pip install requests
py -3 -m pip install requests
This installed requests for Python 3 as well as Python 2.
