android - Buildozer 无法编译 Cython

Question

我正在尝试构建我的 kivy 应用程序，但是运行 buildozer android debug --verbose 我得到的唯一信息如下:

[...]

我正在使用 Archlinux，64 位，python2 2.7.8-2，和 aur/python2-kivy-git。

当我尝试安装 aur/python2-kivy 时，我得到了

我怎样才能让它发挥作用？

Answer 1

这是 Cython 版本 0.21 和旧代码的问题。最简单的解决方案是将 Cython 降级到 0.20，这很有效。

要使用较新的 Cython，请删除下载的 pyjnius 并让 buildozer 下载最新版本:

rm ~/.buildozer/android/packages/pyjnius-master.zip

但是更新的 Cython 也需要更新的 Kivy 代码。在您的 buildozer.spec 中，将需求中的 kivy 更改为 kivy==master 以获取最新的 Kivy 代码。
