libpango-1.0.so.0: undefined symbol: hb_buffer_set_invisible_glyph #63

Closed gschramm closed 2 years ago

gschramm commented 3 years ago

Hi all,

I installed all the dependencies on ubuntu 20.04 following the install guide and manimce via pip install manim. My installed manim version is 0.8 and manimpange is 0.3. When I run 

from manim import *

I get the error:

ManimPango could not import and load the necessary shared libraries. This error may occur when ManimPango and its dependencies are improperly set up. Please make sure the following versions are what you expect:

ManimPango v0.3.0, Python v3.7.7

Original error: /usr/lib/x86_64-linux-gnu/libpango-1.0.so.0: undefined symbol: hb_buffer_set_invisible_glyph

Any idea what is causing this?

Georg

Hi, sorry for the super delayed response I missed this notification. hb_buffer_set_invisible_glyph is a symbol from harfbuzz and the error seems to point that libpango-1.0.so.0 has a reference to it but it is missing. I think the simplest, fix I would suggest is force reinstalling ManimPango.

pip install ManimPango --force --no-cache

Hope this helps :)

I'm having this same issue and reinstalling manimpango did not help
