uwsgi from python2.7 to python3

[António Ramos]

hello i´m using webfaction and this script 

https://github.com/duducosmos/webfaction-web2py-nginx-uwsgi-installer/blob/master/install.py 

that installed web2py a loong time ago.

now i want to use python3.5.9 already available as python3 instead of python 2.7

i read this in the start conf

#!/bin/bash

# Start uwsgi

/home/ramstein74/webapps/new2py/bin/uwsgi   --uwsgi-socket "/home/ramstein74/webapps/new2py/uwsgi.sock"   --master   --workers 1   --max-requests 10000   --harakiri 60   --daemonize /home/ramstein74/logs/user/uwsgi_new2py.log   --pidfile /home/ramstein74/webapps/new2py/uwsgi.pid   --vacuum   --chdir /home/ramstein74/webapps/new2py   --python-path /home/ramstein74/webapps/new2py/lib/python2.7   --wsgi-file /home/ramstein74/webapps/new2py/web2py/wsgihandler.py 

# Start nginx

/home/ramstein74/webapps/new2py/bin/nginx

changing python2.7 to python3 does not work.

Any ideas would be awesome :)

Have you already installed the python-3-uwsgi-lib?

pip3 install --no-binary :all: --upgrade uwsgi

Have a try!

Can you use a virtual env or a docker container?

In uwsgi you need to use a separate plugin for each version of Python. You start with a version of uwsgi with no languages compiled in, the OS uWSGI packages are typically built this way. You obtain a different Python plugin for each version of Python that you want to use. Then you run your Python 2 applications with --plugin=python2 and your Python 3 applications with --plugin=python37 for example.
