使用 buildozer 进行 kivy 打包时出错

Question

包装我使用了 kivy 手册中推荐的工具 我用于来自https://kivy.org/#download 的 kivy 打包虚拟机（Oracle 虚拟框和虚拟机设置） 对于 buildozer 安装，我使用了进程 https://github.com/kivy/buildozer，用于 Python 3。 我手动添加到 buildozer.spec 文件行：

requirements = python3crystax,kivy
android.ndk_path = ~/buildozer/crystax-ndk
log_level = 2

包装由下一段文字描述：

我的问题：如果我为 python 3 使用 buildozer 安装，为什么使用 python 2.7？它是我的问题的根源吗？

Answer 1

Buildozer 是一个 Python 模块，它执行一些操作来打包您的应用程序。该模块由它安装到的 Python 版本运行。在您的情况下，您安装了带有 buildozer 的 Python 2。

buildozer.spec 中的要求与您当前的环境无关。这个要求告诉 buildozer 它应该下载哪些配方/模块，如果需要，编译并打包到你的 Android 应用程序中。 python3crystax means buildozer 将在您的 Android 应用程序中打包位于 Crystax NDK（并且已经为 Android 编译）中的 Python 3 以运行它的代码。
