使用Android的buildozer编译基于kivy的apk应用程序，要求bcrypt返回错误ModuleNotFoundError：没有名为'setuptools_rust'的模块

Question

我是新手所以请原谅我的无知..

我正在尝试按照 kivy 说明和 buildozer 文档中的步骤使用 buildozer 编译基于 kivy 的 apk，我已根据我的要求编辑了 buildozer.spec 文件。

我的 kivy 应用程序在运行 python 3.12.1 的计算机上运行。

我在同一台计算机上使用 Ubuntu wsl 使用 buildozer 编译 apk，其中包含 python 3.10.12 （我想知道这是否是令人困惑的事情）

我的Ubuntu机器使用的是python 3.10.12，pip版本23.3.2，kivy版本2.3.0。

当我运行

buildozer -v android debug

命令时，我不断收到错误：

我的buildozer.spec文件如下：

[app]

我已经尝试了错误中建议的内容并升级了pip，我尝试直接使用pip安装setuptools_rust，它说它已经满意了。

我已经通过从我的要求中删除 bcrypt 成功地从 buildozer 中获取了 apk 文件，但该应用程序无法在我的手机上运行。

我也尝试在我的 Ubuntu 机器上使用 python 版本 3.12.1，但 Buildozer 返回 bcrypt 的 distutils 错误...即使 bcrypt 正在使用该版本的我的应用程序中运行。

我尝试将 setuptools_rust 添加到我的 buildozer.spec 文件中的要求中。

我不确定是否正确填写了 buildozer.spec 文件。非常感谢任何帮助。

我觉得我有点在追自己的尾巴，希望有人能给予一些指导。

查兹，

在上面提供的代码序列中，“source.dir = .”的目录很重要吗？是红色的？最后一行中的“bin”也是红色的：-

(str) main.py 所在的源代码

源.dir = .

（列表）要包含的源文件（留空以包含所有文件）

source.include_exts = py,png,jpg,kv,atlas,csv

(list) 使用模式匹配的内含物列表

source.include_patterns = 资产/,图片/.png,媒体/,插件/

（列表）要排除的源文件（留空不排除任何内容）

#source.exclude_exts =

(list) 要排除的目录列表（留空不排除任何内容）

source.exclude_dirs = 测试、bin、.venv
