Here is how I start django with uWSGI.

command = /usr/local/bin/uwsgi --loop gevent --socket 127.0.0.1:8070 --processes 2 --pp =/home/ubuntu/workspace/htFrontEnd/htdjango --wsgi-file =/home/ubuntu/workspace/htFrontEnd/htdjango/wsgi.py -b 32768 --master --async 20 --enable-threads --listen 2048

Here is the error I get in the logs....

The location of wsgi.phy is correct: /home/ubuntu/workspace/htFrontEnd/htdjango/wsgi.py

Here is my wsgi.py file.

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "htdjango.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

回答1:

it is a typo:

remove the = (equal sign) from =/home/ubuntu/workspace/htFrontEnd/htdjango/wsgi.py and from =/home/ubuntu/workspace/htFrontEnd/htdjango

回答2:

I noticed that this is already happening - added =/home/ubuntu/workspace/htFrontEnd/htdjango to pythonpath. but just to be sure, can you add in one more line into your wsgi.py file -

`sys.path.append('/home/ubuntu/workspace/htFrontEnd/htdjango')`

And let me know if anything else changes in your stdout when you try running it again.

There is certainly something wrong when application = get_wsgi_application() happens as this error message is telling us that uwsgi cannot find our django application.

Are you using virtualenv by any chance? And your django library is in virtualenv itself?
