I am following the steps outlined here to set up maths animation for educational purposes. I've had to figure out how to configure all the steps for Python 3.7, but that hasn't posed any major problems. However, I'm now running into errors I can't quite understand, which seems to come from the pycairo package (I've highlighted the errors in bold below). I tried following the steps outlined here to fix the errors, but although I have successfully installed the latest pycairo package (1.17), I continue to get the same errors. I've got some programming experience but I'm brand new to python so I'm not sure how to resolve the issue. Any help would be greatly appreciated.

I've posted the code below (bolded the errors):

  • This is a known issue: [here](https://github.com/3b1b/manim/issues/292), [here](https://github.com/3b1b/manim/issues/524) and [here](https://github.com/3b1b/manim/issues/751). I solved this issue myself with `brew install pkg-config` but that was on MacOS. – applemonkey496 May 13 '20 at 23:33

it appears that you are using anaconda. From what i see, there seems to be some issues when building the wheel for pycairo. Probably you could try installing pycairo manually and then reinstalling manimlib again in the anaconda prompt.

conda install -c conda-forge pycairo

source - conda-forge/pycairo

I have got problem with pycairo. And I have done solved by the step.

You need to sure dependencies of correct version.

To downgrade them, first uninstall:

pip uninstall Pillow idna requests urllib3

Then you should install with specific versions:

pip install Pillow==5.3.0 idna==2.6 requests==2.18.4 urllib3==1.22
