Does fabric (http://docs.fabfile.org/en/1.7/) support Python 3 yet. As per Python 3 Wall of Superpowers it does not yet. If not what is the best alternative if using Django
You could also create a separate python2.7 virtualenv just for fabric:
sudo virtualenv --no-site-packages -p /usr/bin/python fabric-env
source /var/www/APPNAME/fabric-env/bin/activate
sudo /var/www/APPNAME/fabric-env/bin/pip install fabric
deactivate
Then:
/var/www/APPNAME/fabric-env/bin/fab -f /var/www/APPNAME/fabfile.py FAB_COMMAND
