I faced the same error when installing pycario, do I have to install cairocffi first?

Hi! I solve this problem with this code

export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
export LDFLAGS="-L/usr/local/opt/libffi/lib"

and install pycairo

pip install pycairo

Thanks for your help!

Yes, I’m using Visual Studio Code. I ran these codes and tried again and terminal showed this

The problem is that I do not know if you are trying to install it in the main version of python or in a virtual environment, the last comment you are no longer in virtualenv:

Tests-MacBook-Pro:manim-master test$ python3 -m manim example_scenes.py WarpSquare -pl

You are no longer in the environment (base), as in the previous ones. If you want to install manim in the main version of python then install the pip packages again, BUT without the virtualenv:

Tests-MacBook-Pro:ManimInstall test$ python3 -m pip install -r requirements.txt
Tests-MacBook-Pro:ManimInstall test$ python3 -m pip install pyreadline
Tests-MacBook-Pro:ManimInstall test$ python3 -m pip install pydub
