Is it a license violation to use ExtJS packages from pypi.python.org?

Question

Python

Hello!
Everyone knows that ExtJS is a paid, very powerful JavaScript library for SPA development. Its license allows free use in projects that will be distributed under the GPL. However, I want to make a project that will be closed source, but I can't afford to buy a license for x amount. Will I violate the ExtJS license if I install this library via pip install? For example, this:
pip install django_extjs4
Searching pypi.python.org yields many more packages, but don't they violate the license?

Answer 1

It doesn't matter where you got the ExtJS code from, it only matters how you use it.
