I am running PyCharm 2021 EDU (updated) with a Python 3.8.2 installation on a Windows 10 OS. I am running LibreOffice 7.2.5.2 - so all applications should be at speed. I recently installed pyoo using pip. I am attempting a very simple startup script:

# PyCharm / LibreOffice Interface
import pyoo

desktop = pyoo.Desktop('localhost', 2002)

ss1 = desktop.create_spreadsheet()

which fails with

Traceback (most recent call last):
  File "H:/Projects/Prj_01/Python/main.py", line 3, in <module>
    import pyoo
  File "C:\Users\tradice\AppData\Roaming\Python\Python38\site-packages\pyoo.py", line 18, in <module>
    import uno

    from base import Element, Css, Payload, UnoBaseFeature, UnoBaseField
ModuleNotFoundError: No module named 'base'

When I attempt to use pip in install "base" I get

 error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.

I Apologize that I am a newbie at this - I cannot seem to locate a similar issue in searching... (Or too many responses to be of use...)

(I get the same error regardless of setting soffice running with the pipe activated...)

Would anyone care to venture a hint?
