How do I install mod_wsgi on Mac (High Sierra)?

Question

I'm using Mac 10.13.6 (High Sierra) with this version of Apache ...

localhost:mod_wsgi-4.6.5 davea$ httpd -version
Server version: Apache/2.4.33 (Unix)
Server built:   Apr  3 2018 17:54:07

How do I install the mod_wsgi module so that Apache can load my Python site? I tried using pip but got the most baffling permission errors despite the fact I'm using sudo ...

(venv) localhost:tmp davea$ sudo pip install mod_wsgi
The directory '/Users/davea/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Requirement already satisfied: mod_wsgi in /Users/davea/Documents/workspace/mainpage_project/venv/lib/python3.7/site-packages (4.6.5)
You are using pip version 19.0.1, however version 19.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

The instructions outlined under the link below, work under OSX 10.14 (Mojave):

Based on your output, it seems you are hitting some permission issues.
