ERROR durring import external Libarys in PyCharm for ESP32/Micropython

Hello, i tried the last hours to import external micropython libarys for ESP32 Programming to PyCharm. But with out access. I tried the follow ones via "Phyton Packages" and "Add Packages":

https://github.com/lemariva/uPyLoRaWAN

https://github.com/MZachmann/LightLora_MicroPython

https://github.com/wybiral/micropython-lora

Most of the time the error is: 
ERROR: file://C:\Users\marti\Downloads does not appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' found.

This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

Encountered error while generating package metadata.

ModuleNotFoundError: No module named 'machine'

Why its so difficult to at micropython libarys from git to pycharm?
