Kivy Buildozer在setup.py中返回错误的退出状态1

Question

我正在使用kivy和kivymd制作一个android应用程序。因此，我遵循了buildozer文档页面上的所有说明，我面临一个错误。我使用的模块是kivy,kivymd,datetime,sqlite3(所有这些模块都是用纯python编写的，或者包含一个菜谱)。

我在buildozer.spec文件中输入了所有这些内容。

我正在一个虚拟环境中运行buildozer，该环境在Ubuntu(20)的最新版本上有python3.7。

这是出现在错误之前的内容：

[INFO]:    -> running python3 -m venv venv
[INFO]:    Upgrade pip to latest version
[INFO]:    -> running bash -c source venv/bin/activate && pip install -U pip

[INFO]:    IF THIS FAILS, THE MODULES MAY NEED A RECIPE. A reason for this is often modules       compiling native code that is unaware of Android cross-compilation and does not work without additional changes / workarounds.
[INFO]:    -> running bash -c venv/bin/pip install -v --target '/home/guhan/...(and 146 more)

，这是之后的错误

相同的错误在日志中出现两次。

datetime是一个内置的python模块，它附带了python。您不需要在您的requirements文件中指定它。只需将其从需求中移除并重新运行buildozer即可。
