Question

The big picture is that I want Ubuntu server with nginx, uWGI, and Python 3 (virtualenv) to start some project.

I did follow recommendation that can be found on vari

Answer 1

Install Python 3:

sudo apt-get install python3

Install Python 3 headers to build uWSGI from source:

sudo apt-get install python3-dev

Create a Python 3 virtualenv in a venv subdir of current dir (prepend the command with sudo if current dir is privileged):

virtualenv -p python3 venv

Activate the venv to be the target for pip (. is a shortcut for source):

. venv/bin/activate

Finally, install uWSGI (again, sudo if in a privileged dir):

pip install uwsgi
