Apache Configuration Question

Django + mod_wsgi + apache2: ImportError: No module named <project>

I'm trying to get to the bottom of my problem regarding running any "migrate" command on my django project.
I have a django app deployed in a virtual env and with mod_wsgi and apache2 the app is served properly at www.mysite.com/test/simulatore.
The problem came when I edited the models, so I had to run

python manage.py makemigrations


After some initial troubleshooting I think I have isolated the problem on wsgi.py

If I try (from my virtualenv) to try to run the command

python -i /home/carma/mycarma_test/mycarma/mycarma/wsgi.py


this is the result

['/home/carma/mycarma_test/mycarma/mycarma', '/home/carma/mycarma/testenv/lib/python35.zip', '/home/carma/mycarma/testenv/lib/python3.5', '/home/carma/mycarma/testenv/lib/python3.5/plat-x86_64-linux-gnu', '/home/carma/mycarma/testenv/lib/python3.5/lib-dynload', '/usr/lib/python3.5', '/usr/lib/python3.5/plat-x86_64-linux-gnu', '/home/carma/mycarma/testenv/lib/python3.5/site-packages', '/home/carma/mycarma_test/mycarma/mycarma/..', '/home/carma/mycarma_test', '/home/carma/mycarma_test/mycarma']

ImportError: No module named '”mycarma'


As you can see the module mycarma (which is the project name) is reported with single quotes and the just the initial double quote

ImportError: No module named '”mycarma'


This tells me (I think) there is a configuration issue somewhere that is passing a wrong parameter, but I can't find where. Here are my settings:

File wsgi in mycarma/mycarma

import os
import sys

from django.core.wsgi import get_wsgi_application

DJANGO_PATH = os.path.join(os.path.abspath(os.path.dirname(__file__)), '..')
sys.path.append(DJANGO_PATH)
sys.path.append('/home/carma/mycarma_test')
sys.path.append('/home/carma/mycarma_test/mycarma')
print(sys.path)
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mycarma.settings")

application = get_wsgi_application()


Please note I added the two append and the print in order to test/troubleshoot. But also without them no luck.
settings.py

ROOT_URLCONF = 'mycarma.urls'
STATIC_URL = '/static/'
STATIC_ROOT = '/home/carma/mycarma/static'

Thanks.

EDIT: problem found
In the dev bin/activate script the

DJANGO_SETTINGS_MODULE=”carma.test_settings”


used some weird double quotes. Modified and everything si working.

Answer

I am pretty sure that is because you have that extra double quote in your INSTALLED_APPS django config. This is happening when django bootstraps and tries to load all your apps and it can't locate it.
