Kivy + Python3 on OSX environment maintenance
I learned that I could write iOS / Android apps with Python, and tried to improve the environment immediately, but it took a lot of time, so I made a note. Official documentation here.
Required package installation
Various libraries
Kivy depends on pygame, and you need to pre-install the SDL libraries that pygame depends on, and libpng to avoid errors when installing freetype, which sdl_ttf depends on. Must be installed with --universal. It's complicated ...
brew reinstall libpng --universal
brew install sdl sdl_image sdl_mixer sdl_ttf portmidi
Install from source
How to clone the repository and then install it normally
Get the sauce.
git clone --depth 1 -b 1.9.0 --single-branch https://github.com/kivy/kivy.git
git clone --depth 1 -b 0.21.2 --single-branch https://github.com/cython/cython.git
First, build and install Cython.
cd cython
python3 ./setup.py build
sudo python3 setup.py install
Build and install Kivy as well.
python3 setup.py build_ext --inplace -f
sudo python3 setup.py install
Confirm that it is installed.
pip3 list | grep -e Cython -e Kivy
Cython (0.21.2)
Kivy (1.9.0)
How to specify the repository directly in pip
If you do the following, you can directly specify the repository and install it without git clone each time.
sudo pip3 install git+https://github.com/kivy/[email protected]
sudo pip3 install git+https://github.com/cython/[email protected]
Sample code execution
When I ran the sample code on the Kivy official website, the OS X UI was displayed. With this, I was finally able to stand on the starting line.
#!/usr/bin/env python3
# -*- coding:utf-8 -*-
from kivy.app import App
from kivy.uix.widget import Widget
class PongGame(Widget):
pass
class PongApp(App):
def build(self):
return PongGame()
if __name__ == "__main__":
PongApp().run()
