适用于Mac OS X的Kivy for Python 3

Question

I was wondering if kivy supports Python 3 on Mac OS X systems. From the download page from the kivy official website, it seems that kivy-1.9.0 is available for Python 3.4 for Windows systems, but it does not seem to support Python 3 on Mac OS X:

Mac OS X Mac OS X 10.9, 10.10 (requires Python 2.7)
Kivy-1.9.0-rev3-osx.dmg (Mirror)

This seems a little but nonsensical, why kivy should support Python 3 on Windows but not on a Mac OS X? It could be because of the missing support of PyGame for Python 3 for OS X systems? Actually, there's a way to install PyGame for OS X systems for Python 3, so I do not understand why they do not fix this problem, if this is really a problem.

I have also tried to install it globally via pip3 using:

sudo pip3 install kivy

But I am getting the following error:

Collecting kivy Downloading Kivy-1.9.0.tar.gz (16.2MB) 100% |████████████████████████████████| 16.2MB 34kB/s Complete output from command python setup.py egg_info:

Answer 1

You will need to build from source .

As a previous poster mentioned, you will need to get Cython installed.

To get the latest version, use

$ pip3 install cython

From there, you need to modify setup.py. Here's an example of how I did it.

Answer 2

According to the error message, you are missing the package cython :

Cython is missing, its required for compiling kivy !
...
ImportError: No module named 'Cython'

You should run pip install cython . Then installing from source worked for me, by opposition to using pip .
