Answer 1

This arises from a change in cython a while ago. You can avoid it by either installing kivy from the github master branch rather than pypi (there is a pip syntax for this), or by downgrading cython, possibly to 0.21.

Answer 2

Python 2.7 MacOS 10.12

I was trying to install Kivy on my mac(sierra), it took me quite sometime to figure it out. Give this a shot.

Install Cython with downgraded version

pip install 'Cython===0.26.1'

From the documentation it asked you to install Cython, by

pip install -U Cython

but it couldn't compile when installing Kivy, and I found in Kivy's git repo, it didn't use the latest version of Cython, instead if uses version 0.26.1

Installing Kiwy by

pip install --user kivy

Without the --user flag it will throw an error saying

“OSError: [Errno 1] Operation not permitted”

Good Luck.
