@RomanOnARiver So here's the thing: don't assume that any time you're asked to do something differently it's a change for the worse. (see also https://xkcd.com/1172/) You didn't say what pip is actually saying when it yells at you, but if it's the thing that most often generates these kinds of complaints - the "externally managed environment" warning message - you were doing it wrong all along, and pip just never told you before.

The new way is to use a virtual environment for each situation where you need to install things. There are many ways to create and manage virtual environments - the simplest being `python -m venv <path>` - and once you have one, you can use pip to install your packages in that environment, e.g. with `<path>/bin/python -m pip install wxPython`. (Or `<path>/bin/pip install wxPython` probably works too, but there are some weird niche cases where that runs into trouble.)
