Overnight django stopped working, possibly because of an automatic package upgrade on the server. Its wsgi script now fails to load in production, but running the development server works fine. What might cause the following error?



mod_wsgi (pid=27634): Target WSGI script '/var/www/.../wsgi.py' cannot be loaded as Python module.
mod_wsgi (pid=27634): Exception occurred processing WSGI script '/var/www/.../wsgi.py'.

The wsgi.py file is as follows:

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "....settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()


This worked 24 hours ago and has stopped working - I've tried django 1.10 and 1.10.3 but both exhibit the same symptoms. apache 2.4.18, python 2.7.12.



The file /usr/local/lib/python2.7/dist-packages/django/db/models/signals.py exists, so in principle there shouldn't be anything stopping the import.

          It turns out that there was a file that was not readable by the webserver, and an earlier line in the error log identified this file.
