How do I get mod_wsgi for Apache2 that was compiled for Python 3.6.1?
(or any future Python version)
I am using a Python 3.6.1 virtual environment with Django 1.11 and Everything is working according to the Apache error log except that mod_wsgi for Apache 2.4 was compiled for Python/3.5.1+ and is using Python/3.5.2 so my Python 3.6.1 code is failing because I'm using new features not available in 3.5.2
All of the other configurations and installs involved in setting my system up seem to be fine (Running in daemon mode) though mod_wsgi doesn't seem to be using my Python 3.6.1 virtual environment (though it is trying to use it for Django according to the error log)...
I used: sudo apt-get install libapache2-mod-wsgi-py3 to install mod_wsgi for Apache 2.4
I used: ./configure --with-python=/usr/local/bin/python3.6 and make with make install to install mod_wsgi for Python 3.6
I must be doing something wrong - please correct me!
Here is my Apache Error Log (cleaned a bit) - and yes I know it fails on the f"" string line (python 3.6 feature not in 3.5)

Do the following.
Uninstall your system mod_wsgi package.
sudo apt-get remove libapache2-mod-wsgi-py3
Install mod_wsgi using pip, preferably into a Python virtual environment. Ensure pip is for the version of Python you want to use.
pip install mod_wsgi
Display the config to add to Apache configuration file to load this mod_wsgi by running:
mod_wsgi-express module-config
Take the output of above command to display config and add to Apache configuration.
Add configuration to Apache to load a hello world WSGI application to test it works.
See details for pip based install in:
When I have used the @Graham Dumpleton suggestion to install the mod_wsgi using pip, got this error:
RuntimeError: The 'apxs' command appears not to be installed or is not executable.
Please check the list of prerequisites in the documentation for this package and
install any missing Apache httpd server packages.
To successfully compile and install the mod_wsgi through pip, I need to install the apache2-dev package on Ubuntu:
sudo apt-get install -y apache2-dev
After that pip install mod_wsgi completes successfully.
Hope that might help others.
