【问题描述】：

在我的系统上安装 kivy 时遇到很多麻烦。我以前做过这个工作，但由于某种原因，我现在过得很艰难。 我按照指示逐字执行，设置 virtualenv，激活 env，安装依赖项（docutils、pygments、pypiwin32、kivy_deps.sdl2==0.1*.、kivy_deps.glew==0.1*.、kivy_deps.gstreamer==0.1。 *)。

上面的所有部分都可以正常工作。当我终于去安装 kivy (py -m pip install kivy) 时，我得到了一连串的错误：

我也尝试过使用夜间备份，安装***，尝试 tar.gz；但我在这里很困惑。

【问题讨论】：

我认为 Kivy 还不支持 Python 3.8。它的 PyPI 项目页面 pypi.org/project/Kivy 和它的 Windows 安装说明 kivy.org/doc/stable/installation/installation-windows.html 都说不。

-__- 真是个疏忽。 - 所以当一个包被标记为“cp38”时，这是否意味着它与 python 3.8 的兼容性？我想这个命名法让我相信 3.8 是稳定的 kivy.org/downloads/appveyor/kivy

我不是 Kivy 专家，所以我对命名法无话可说。但是你的问题说它曾经可以工作，这在我脑海中敲响了升级警报。

【参考方案1】：

我们目前不为 Windows 上 Python 3.8 下的最新 Kivy 稳定版本提供***。您的选择是：

设置工作编译器工具链并自己编译 Kivy 使用 Python 3.7 使用 Kivy master 分支，它确实有 Python 3.8 ***可用 - 我不记得是怎么知道的，但最坏的情况是 Kivy discord 上的某个人会知道

请注意，最新的 Kivy 稳定版本确实支持 Python 3.8，它运行良好，这就是第一个选项可用的原因。问题完全在于缺少预构建的二进制文件。

【参考方案2】：

easy_install kivy 有效（但 easy_install 已弃用，所以要小心）
