Python Mac下安装pygame

1. 需要先安装pygame的依赖库

brew install hg sdl sdl_image sdl_ttf

否则会出现一下错误

2. 如果要启用Pygame的更高级功能，如游戏中包含声音，还需要安装以下库

brew install sdl_mixer portmidi

3. 接下来安装pygame

pip3 install pygame

默认安装的是当前发布的正式版本（1.9.6），但是在mac10.15上无法跑起来（可能之前的几个版本也跑不起来）
需要安装2.0的开发版

pip3 install pygame==2.0.0.dev10（最新的，也可以安装dev6）
