Hello @jalsco, it'd be much more convenient for other people trying to help you if you pasted the error you received in text form instead of a hardly readable screenshot. Not everybody is able to decipher dark red text on a dark background, and some people rely on screen readers or other accessibility tools.

First, please state the exact steps you took while installing. Which debian packages did you install before attempting to run the pip command that errors out for you?

Second, installing isso directly via pip from the master branch is not one of the documented options.

Third, since you helpfully pasted the log of the error you received, here's the important part:

[...]
fatal error: pyconfig.h no such file or directory
[...]
compilation terminated

Researching the issue surfaces a few solutions which you might try, for example this one.

The isso documentation for installation instructs you to install following system packages before attempting to install isso via pip:

sudo apt-get install python-dev sqlite3 build-essential

For python3, that should be python3-dev (since Debian sadly still seems to default to python2). So your issue seems to be that you do not have the correct python development package installed.

If you'd like, you can open a Pull Request to change that in the documentation. Isso does not support python2 since #613.

Thank you for your reply. I will try those steps and report back.
Also - since posting that I have upgraded to Debian 11 (bullseye), Python 3.9.

@jalsco did you ever get to test out the suggestions presented to you?

If so, would you mind creating that PR to the documentation to help out others with the same issue?
