ImportError: No module named django.core.wsgi (ubuntu)

Question

I am following this guide to configure apache for my django web application:
https://docs.djangoproject.com/en/1.9/howto/deployment/wsgi/modwsgi/#basic-configuration

I have installed Django, mod_wsgi-express (the new way) and mod_wsgi for apache on an ubuntu 15.10 server using:

pip install Django
pip install mod_wsgi
sudo aptitude install libapache2-mod-wsgi

Next I have added the below to: /etc/apache2/apache2.conf

WSGIScriptAlias / /home/user/mysite/mysite/wsgi.py
WSGIPythonPath /home/user/mysite:/home/user/.local/lib/python2.7/site-packages

<Directory /home/user/mysite/mysite>
<Files wsgi.py>
Require all granted
</Files>
</Directory>

But when I start apache I get the below error:

[Sat Mar 26 12:10:06.876025 2016] [wsgi:error] [pid 10622:tid 139806697674496] [client 217.40.250.17:52124]     from django.core.wsgi import get_wsgi_application
[Sat Mar 26 12:10:06.876057 2016] [wsgi:error] [pid 10622:tid 139806697674496] [client 217.40.250.17:52124] ImportError: No module named django.core.wsgi

But that module indeed exists in the path I have supplied in WSGIPythonPath above:

~/.local/lib/python2.7/site-packages/django/core $ cat wsgi.py
import django
from django.core.handlers.wsgi import WSGIHandler

And:

~/.local/lib/python2.7/site-packages $ ll
total 24
drwx------  6 user user 4096 Mar 24 22:25 ./
drwx------  3 user user 4096 Mar 20 20:56 ../
drwxrwxr-x 17 user user 4096 Mar 24 22:25 django/
drwxrwxr-x  2 user user 4096 Mar 24 22:25 Django-1.9.4.dist-info/
drwxrwxr-x  5 user user 4096 Mar 20 20:59 mod_wsgi/
drwxrwxr-x  2 user user 4096 Mar 20 20:59 mod_wsgi-4.4.22.egg-info/

I also tried to validate the version of python the mod_wsgi module was build against:

 /usr/lib/apache2/modules $ ldd mod_wsgi.so
    linux-vdso.so.1 =>  (0x00007ffe50f31000)
    libpython2.7.so.1.0 => /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 (0x00007f376fbc2000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f376f9a4000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f376f5d9000)
    libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f376f3bf000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f376f1bb000)
    libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007f376efb7000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f376ecaf000)
    /lib64/ld-linux-x86-64.so.2 (0x00005609838b3000)

So it appears it was build against Python 2.7 which is the same version Django is being installed under.

So why does apache fail to load my application/django?

Answer 1

Based on:
http://www.webforefront.com/django/setupapachewebserverwsgi.html

the www-data user (user running apache folder) must have read access to the folder containing the django installation. I just did a test where I copied the django installation and my web application to: /var/www/test and changed the permission for that folder:

sudo chgrp -R www-data /var/www/test
sudo chmod -R g+rwx /var/www/test

and the application now loads.

Answer 2

I got this error just now when I was trying to set up my Django, Nginx and WSGI according to this tutorial: https://uwsgi.readthedocs.io/en/latest/tutorials/Django_and_nginx.html

When I typed in the command: uwsgi --http :8000 --module mysite.wsgi

I get the error:

from django.core.wsgi import get_wsgi_application ImportError: No
module named django.core.wsgi

It made no sense to me because when I entered the python shell in my virtualenv and imported the module, it worked perfect.

However, I found this tutorial to be useful in getting rid of the error: https://gist.github.com/evildmp/3094281

uwsgi --http :8000 --module project.wsgi --virtualenv /path/to/virtualenv

Typing in the path to your virtualenv causes WSGI to find the module it was missing.

You can find the path to the virtualenv by typing in $ECHO virtualenv in your command prompt / terminal.

I had the same issue.

Reason being that I had installed gunicorn via apt, which was then running in the system-wide Python 2 installation, instead of my venv.

Fixed it by uninstalling the system gunicorn, and then activating my venv, and installing gunicorn to the venv using pip install gunicorn. Then it worked straight away.

Run these commands:

$ sudo apt-get remove libapache2-mod-python libapache2-mod-wsgi

$ sudo apt-get install libapache2-mod-wsgi-py3
