total NixOS newbie here.
I want to install pip packages in NixOS but got several Errors.
When i want to install pip packages via terminal and
pip install npyscreen I get the following error:
WARNING: You are using pip version 20.1.1; however, version 21.3.1 is available
It also said that I use python 3.8 but when I run
pyhton3 it show me the Version 3.9.
My question: Why is using NixOS the older python version and how do I upgrade pip and install the packages?
Thanks and sorry for not-knowing
