Kivy Python 3.4 osX installation failure

Question

I get this error when trying to install kivy. I used the command "pip install kivy". I have already installed pygame and cython

You might get a more useful response by asking the devs or filing a bug report at github.com/kivy/kivy — Azsgy

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.
