OSError: no library called "cairo-2" was found

[tejaswi-devalla]

Installed the new version
Tried to test:
from Custom_Widgets.ProgressIndicator import test
test.main()

It kept throwing the same error. What's the problem?

Hi,
you must install package named cairocffi, it's special package, which you can't install with classical pip.

Firstly install package named pipwin:
pip install pipwin

Then just install cairocffi package through installed pipwin package:
pipwin install cairocffi

Hi,

I get the same error, I tried GTK install, and the pipwin command, it doesn't appear to work on Mac?

While I load 'Custom_Widget' in python, I faced same issue on 'cairo'.
I did install cairocffi and GTK3-runtime program, too.
Do you have any idea to solve these errors?

Thank you.

Make sure, you are running supported version of Python. I use Python 3.10 and works fine for me.
