tried to install Django
and got the following message: Fatal Error!
Failed to install web app : This web app cannot be installed, as this virtual server does not meet its requirements : Missing command pipFatal Error!
Try installing the OS package python3-pip and try again.
The Django installer needs some attention, though, as I think it’s using a pretty old/cranky way of running Python apps that was common in the past, but less so now. Unlike PHP apps, there’s never been a universally agreed on app server (like php-fpm for PHP), so what’s considered best practice has evolved a bunch over the years, and I don’t actually know what that is today; last time I made a Python app it was gunicorn (and before that unicorn and something else I don’t remember before that).
Some of what you said is over my head.
In the day I took and used COBOL, FORTRAN w/ Watt 5 assist, PL/I , Assembler 360/370, LISP and of course BASIC that was a long time ago and I got away from programming to much of a headache
The only actionable thing in my comment was “try installing python3-pip”, the rest was general belly-aching about the Python ecosystem being erratic and user-hostile. If you got that one actionable item, you got what you needed most urgently.
