Please install the Cairo library using your Linux distribution’s package manager.

I get similar messages on Windows 11 with Python3.10 when I import cairosvg. Nothing I have tried has eliminated the messages.

Nothing I have tried has eliminated the messages.

On Windows, you can install GTK3 (keeping the default options) and then reboot your computer, it will work.

Thank you for the tips. I have installed GTK3 and rebooted, these are the messages: Windows PowerShell Copyright (C) Microsoft Corporation. All rights reserved.

Install the latest PowerShell for new features and improvements! https://aka.ms/PSWindows

Python found the library in 'C:\Program Files\GTK3-Runtime Win64\bin\libcairo-2.dll', but couldn’t use it for some reason. And to be honest, I have no idea why :/.
