Manim: OSError: dlopen() failed to load a library: cairo / cairo-2 / cairo-gobject-2'`

[liangpu597]

I used python3.
I use pip install pycairo
F:\3Blue1Brown\manim-master>python extract_scene.py example_scenes.py SquareToCi rcle -pl Traceback (most recent call last): File "extract_scene.py", line 15, in <module> from scene.scene import Scene File "F:\3Blue1Brown\manim-master\scene\scene.py", line 17, in <module> from camera.camera import Camera File "F:\3Blue1Brown\manim-master\camera\camera.py", line 10, in <module> import cairocffi File "C:\Users\Tony\AppData\Local\Programs\Python\Python36-32\lib\site-package s\cairocffi\__init__.py", line 41, in <module> cairo = dlopen(ffi, 'cairo', 'cairo-2', 'cairo-gobject-2') File "C:\Users\Tony\AppData\Local\Programs\Python\Python36-32\lib\site-package s\cairocffi\__init__.py", line 38, in dlopen raise OSError("dlopen() failed to load a library: %s" % ' / '.join(names)) OSError: dlopen() failed to load a library: cairo / cairo-2 / cairo-gobject-2'

Same for me; have you found a fix yet?

I am on mac10.13/python3.7. My error message is slightly different but must be related to the same issue.

ImportError: dlopen(/Users/ishandutta2007/.pyenv/versions/3.7.0/lib/python3.7/site-packages/cairo/_cairo.cpython-37m-darwin.so, 2): Symbol not found: _cairo_xcb_surface_set_size

[ishandutta2007]

This worked for me(mac10.13/python3.7.), not sure if the first line is required though, now I have pycairo 1.18.0 instead of 1.17.1 as in requirements.txt

pip install cairocffi
pip uninstall pycairo
pip install pycairo

PS: Here pip is alias for pip3

[Elteoremadebeethoven]

Install Homebrew: https://brew.sh/
Write in terminal:

$ brew install cairo --use-clang
$ brew install py2cairo
$ brew install pkg-config

And then write in the folder of manim-master

python3 -m pip install -r requirements.txt

Closing, as this issue seems to be resolved.
