如何从 Python 3.5 降级到 Python 3.4

问题描述

我想安装 kivy(链接在这里) 用于项目，但是，当尝试使用 pip 安装它所依赖的包时，我收到以下错误:

I want to install kivy (link here) to use for a project, however, when trying to use pip to install the packages it is dependent upon, I get the following error:

Could not find a version that satisfies the requirement kivy.deps.sdl2 (from versions: )
No matching distribution found for kivy.deps.sdl2

在 kivy 网站上的进一步阅读显示，由于某种图形错误，这些库不支持 Windows 10 上的 Python 3.5.该网站说您需要 python 3.4 才能安装它.

Further reading on kivy's website revealed that these libraries do not support Python 3.5 on windows 10 because of some kind of graphical bug. The website says you need python 3.4 in order to be able to install it.

这就带来了一个问题:我已经有了python 3.5，如何安装python 3.4?

Which brings the question: How do I install python 3.4 when I already have python 3.5?

推荐答案

到控制面板卸载Python 3.5，卸载一个程序，然后寻找Python 3.5，点击它并按下卸载.之后下载 Python 3.4.我不知道任何其他方法，但我认为这应该有效.

Uninstall Python 3.5 by going to control panel, uninstall a program, and then look for Python 3.5, click on it and press uninstall. After that download Python 3.4. I don't know any other ways but I think that should work.
