How to fix error when installing kivy 2.0 on python 3.8.8 (could not find a version that satisfies...)?

Question

Python

I can't install Kivy 2.0.0 on Python 3.8.8 (x64), OS Windows 7 x64 Pro sp1, I write the code on PyCharm ComEd 2021.1.1. The Internet is not connected to the PC, so you have to install it through the terminal and the wheel.
I install it in the terminal using the command:

python -m pip install c:\\users\юзер\appdata\local\programs\python\python38\Kivy-2.0.0-cp38-cp38-win_amd64.whl

Gives an error:

ERROR: Could not find a version that satisfies the requirement Kivy-Garden>=0.1.4 (from Kivy==2.0.0) (from versions: none)

ERROR: No matching distribution found for kivy-garden>=0.1.4 (from Kivy==2.0.0)

I don’t understand what I’m doing wrong, I googled for a couple of days, I didn’t find a solution, tell me please !!!
