Installing python package 'processing'

Question

I'm new to python and pycharm and getting an error installing the processing package. Other packages have installed successfully. I'm been using PyCharm's package installer. However when I type pip install processing at the command line I also get an error. My version of PyCharm is 2022.1. Command output from PyCharm is:

Collecting processing

  note: This error originates from a subprocess, and is likely not a problem with pip.

WARNING: You are using pip version 22.0.3; however, version 22.0.4 is available.
You should consider upgrading via the 'C:\Program Files\QGIS 3.22.5\bin\python.exe -m pip install --upgrade pip' command.

Answer 1

That package is 14 years old – it's from 2008 – and it's Python 2 only.

You can't install it on Python 3, which is what you (or your QGIS) is running.

Chances are you shouldn't be trying to install it either.
