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

[cporrasn]

I have this problem:

OSError: no library called "cairo-2" was found
no library called "cairo" was found
no library called "libcairo-2" was found
cannot load library 'libcairo.so.2': error 0x7e
cannot load library 'libcairo.2.dylib': error 0x7e
cannot load library 'libcairo-2.dll': error 0x7e

I use windows, with a python 3.8.

Installing gtk3 from here: https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer/releases is enough to solve the problem?

Yes, installing with default options and rebooting should be enough.

I previously posted a solution that worked for me on Windows 11. It is closed as far as I am concerned but apparently a person with greater expertise could apply the same fix to the CairoSVG package and completely fix the issue.

When used in Python3.10 on Windows 11, it is not enough to add the GTK3-Runtime Win64 to the path as the dll still does not load correctly. Adding this solves the issue:
gtkbin = r'C:\Program Files\GTK3-Runtime Win64\bin'
add_dll_dir = getattr(os, 'add_dll_directory', None)
if callable(add_dll_dir):
add_dll_dir(gtkbin)
else:
os.environ['PATH'] = os.pathsep.join((gtkbin, os.environ['PATH']))
import cairosvg
