Can't install in LibreOffice: No module named 'dateutil' (or 'dateutil.tz' is unknown)

[Johann-Tree]

I'm using Ubuntu 20.04.5 LTS and LibreOffice 7.3.2.2 .
I cloned the repo, installed Ics.py via
pip install ics
, changed into the directory and then built the extension with
./build.py
When trying to install the extension in LibreOffice, I got following error:

Checking dateutil again:
pip install python-dateutil
returns

Requirement already satisfied: python-dateutil in /usr/lib/python3/dist-packages (2.7.3)

Sorry for answering late, but I had no free time until now.

The file build.py was my first attempt for building the extension based on some examples I found online. For the release 0.1 I used the Makefile in the repository. I just clarified the build instructions in the README file.

If you install all dependencies with pip install ics arrow and follow the instructions it should work.
