uWSGI - ImportError: No module named os

This is puzzling, because uWSGI works when running:

uwsgi --http :8003 --wsgi-file bigsky.wsgi

But doesn't work with:

uwsgi --ini uwsgi.ini --no-site

It returns this error:

Traceback (most recent call last):
  File "bigsky.wsgi", line 1, in <module>
    import os
ImportError: No module named os

This is being deployed with:

Here's the code:

uwsgi.ini:

[uwsgi]
# %d is the dir this configuration file is in

socket = 127.0.0.1:8003
chmod-socket = 666

uid = bsdev
gid = bsdev

master = true
enable-threads = true
processes = 4

# virtualenv
home = /home/bsdev/.virtualenvs/bs_py34

chdir = /www/django/releases/persistent/bsrs/python3/
wsgi-file = project.wsgi

env = DJANGO_SETTINGS_MODULE=project.settings.persistent

# create a pidfile
pidfile = /tmp/project-master.pid 
harakiri = 10 # respawn processes taking more than 20 seconds
max-requests = 5000 # respawn processes after serving 5000 requests

# will be run via `supervisord` so don't need to daemonize
# logto = /var/log/uwsgi/project.log
logdate = true
vacuum = true

project.wsgi:

import os
import sys


# python 3
sys.path.append('/usr/local/bin/python3.4')
sys.path.append('/usr/local/lib/python3.4/site-packages')

# project
sys.path.append('/www/django/releases/persistent/bsrs/python3')
sys.path.append('/www/django/releases/persistent/bsrs/bsrs-django')
sys.path.append('/www/django/releases/persistent/bsrs/bsrs-django/project')
sys.path.append('/www/django/releases/persistent/bsrs/bsrs-django/project/project')


# 1st instantiate wsgi
from django.core.wsgi import get_wsgi_application
_application = get_wsgi_application()

# Add the app directories to the PYTHONPATH
os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings.persistent'


def application(environ, start_response):
    return _application(environ, start_response)

Edit:

I am also getting this error message. It says Python version: 2.7.5, but the Django App should be running in python 3.4. Is this a possible issue?

You are using python3, so install uwsgi with pip3

pip3 install uwsgi

I was having this issue, because I had not compliled uWSGI correctly on Centos 7, and needed to then build it with Python 3.4. In short, here are the commands:

wget http://projects.unbit.it/downloads/uwsgi-2.0.3.tar.gz
tar -xvf uwsgi-2.0.3.tar.gz
cd uwsgi-2.0.3

source ~/path/to/virtualenv_python3.4/bin/activate

python uwsgiconfig.py --build

Then run uWSGI:

sudo ~/misc/uwsgi-2.0.3/uwsgi --ini uwsgi.ini
