Elteoremadebeethoven · 2019-08-01T07:02:37Z

I see what the error is, you are using a virtual environment (I guess it is virtualenv), in your first comment you were not using it.

First comment:

Tests-MacBook-Pro:ManimInstall test$ python3 -m manim example_scenes.py WriteStuff -pl

Second comment:

(base) Tests-MacBook-Pro:ManimInstall test$ python3 -m manim example_scenes.py -pl

If you are going to use a virtual environment you must reinstall all the python packages with pip. In your case:

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

daniel-lara-ec · 2019-08-01T12:19:34Z

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

You forgot the 3 in python:

python3 -m manim ...

daniel-lara-ec · 2019-08-01T20:51:25Z

Oh! yes i looked this. It's my first time with Python but I uninstall all and try to reinstall again but the problem hold. A friend suggest me that this can be a problem with the path of the modules or something related but i don't kwno how solve this.

I tried again and have this

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

Elteoremadebeethoven · 2019-08-01T21:07:32Z

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

daniel-lara-ec · 2019-08-02T00:18:33Z

Well I'm using Visual Studio Code like a terminal

I tryng to solve this problem using

import cairocffi as cairo

but the problem holds

Elteoremadebeethoven · 2019-08-02T01:29:05Z

Try this, go to manimlib/camera/camera.py line 9 in your manim-master folder and replace that line with import cairocffi as cairo

daniel-lara-ec · 2019-08-02T03:34:41Z

I tried this but i have another problem

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

and in problems window have this

Elteoremadebeethoven · 2019-08-02T04:47:40Z

I forgot to tell you that you had to install cairocffi, with pip:

brew install cairocffi cffi CairoSVG lxml
python3 -m pip install cairocffi

And reboot.

Elteoremadebeethoven · 2019-08-02T04:56:40Z

Also check this.

daniel-lara-ec · 2019-08-07T23:51:15Z

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!

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

I ran the following line in the terminal of VS Code and then restarted VS Code. Worked for me!

pip install cairocffi
