如何解决无限循环：“尝试首次构建 kivy 以获取自定义 cython 文件：这预计会失败......工作：kivy/graphics/fbo.c:1:xx：警告：nul......”

我已经构建了一个小推车，我可以使用我使用 Kivy 用 Python 编写的应用程序（下面的代码）来控制它，但是当在虚拟 Linux 机器中使用 Buildozer 和以下命令时（Android 手机通过 USB 插入我的计算机启用调试）：

$ buildozer android debug deploy run logcat

它仍然停留在以下部分：

[INFO]:    -> running python3 -c import sys; print(sys.path)
[INFO]:    Trying first build of kivy to get cython files: this is expected to fail
[INFO]:    -> running python 3 setup.py build_ext -v
           working: kivy/graphics/fbo.c:1:xxxxxxx: warning nul...(and 38 more)

除了 xxxxxxx 之外，整个消息在大约 1.5 小时内保持不变，这是一个不断增加的数字，最近达到了七位数字。

当我使用 PyCharm 在我的 Windows PC 上运行该应用程序时，它运行良好。

任何帮助将不胜感激！
