Kivy 是一套用于跨平台快速应用开发的开源框架,只需编写一套代码,便可运行于各大桌面及移动平台上(包括 Linux, Windows, OS X, Android, iOS, 以及 Raspberry Pi) Kivy 采用 Python 和 Cython 编写,在国外已经十分火爆,受关注程度甚至一度超越了老牌的 Python GUI 工具 PyQt。可惜 Kivy 在国内还鲜为人知,咪博士将会陆续推出一系列 Kivy 中文教程。这一篇先教大家,在 Windows 上 安装 Kivy。
零、准备工作
请确保你的电脑上,已经安装了 Python 3.6, 并且已经设置好了 pip 国内源(国内镜像)。
具体可以参考咪博士此前的 2 篇教程
Python 3.6.3 官网 下载 安装 测试 入门教程 (windows)
Python pip 下载速度慢? Windows 设置 国内源,用 阿里云 国内镜像 加速
一、Windows 下安装 kivy
启动 Windows 命令行窗口
按 Windows 徽标 + R,输入 cmd,再按回车启动 Windows 命令行窗口
pip 安装 kivy 依赖
在 windows 命令行中,执行以下命令
1 python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
2 python -m pip install kivy.deps.gstreamer
- 安装 kivy
在 windows 命令行中,执行以下命令
python -m pip install kivy
- 安装 kivy 官方示例
在 windows 命令行中,执行以下命令
1 python -m pip install kivy_examples
二、验证 kivy 安装
在 Python IDLE 中,依次输入下面的代码(注意缩进)
1 from kivy.app import App
2 from kivy.uix.button import Button
3
4 class TestApp(App):
5 def build(self):
6 return Button(text=‘iPaoMi’)
7
8 TestApp().run()
最后,你将看到执行上面的 Python 代码,会运行如下的窗口,这可以算是 kivy 版的 hello world 了。
通过 kivy 提供的打包工具,你可以将 kivy 程序打包,运行到不同的平台上,包括各大主流的桌面系统和手机上(如 Android, iOS)。关于这些话题,请关注咪博士后续的 kivy 中文教程。
