OSError: no library called "cairo" was found

I have cairo installed and manim is working fine, but I get this error:
OSError: 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
every time I try to run this:
from chanim import *
class ChanimScene(Scene):
def construct(self):
chem = ChemWithName("*6((=O)-N(-CH_3)-*5(-N=-N(-CH_3)-=)--(=O)-N(-H_3C)-)")
self.play(chem.creation_anim())
self.wait()
I had the exact same idea as you - a manim based chemistry animation engine. I stumbled over this project while searching for ways to create such a thing, I really hope I can get Chanim to work it's an awesome project.
Any help is appreciated.
Hmm, could you post the entire traceback please? It most likely is a Pango problem and not specifically related to chanim, but more info would be helpful here, especially since you say the rest of manim is working fine. Send the full traceback here as a comment or pastebin (or alternative) link please.

Thank you for the kind words! I'll admit things are a bit of a mess here right now, I'm trying to patch it up slowly. Support like this gives me all the more motivation to stop slacking and actually put some effort here, haha!
Thank you for the quick response, here's the entire traceback:

I tried to reinstall Pango, but this error unfortunately still shows up - will look into ways around this problem.
