Can't seem to import manimlib or cairo on macOS mojave.

Don’t know if it’s an import error or something else.

1. Steps to reproduce the issue (e.g. the command you ran)

python3 extract_scene.py example_scenes.py SquareToCircle -pl

Ran this in the folder and venv. Get the same error.

2. The unexpected behavior that occurred (e.g. error messages or screenshots)

Traceback (most recent call last):

3. The environment (e.g. operating system and version of manim)

macOS mojave 10.14.5

P.S. This is my first support ticket ever here, so feedback is appreciated.

I see that blog post, which was written September last year, referenced a couple times here. The installation guide is no longer applicable on the current code base.

manim uses subprocess and does not make use of those python wrappers.

pip3 install sox
pip3 install ffmpeg
pip3 install latex

Media output now defaults to manim/videos so modification at step 8 is not necessary.

The command to run example scene is outdated. (though it will probably work still)

I am not sure what step10 is modifying.

tex_template.tex shoud work as is from the current repo.

Uninstalling Anaconda worked! Thanks @Kolloom @vbartle
