Python 无限循环：“无限循环”；尝试第一次构建kivy以获取自定义cython文件：这可能会失败。。。工作：kivy/graphics/fbo.c:1:xx:warning:nul…“；

我已经构建了一个小购物车，我可以使用我用Kivy（下面的代码）用Python编写的应用程序来控制它，但是当在虚拟Linux机器中使用Buildozer并使用以下命令时（Android手机插入我的计算机并启用USB调试）：

它仍然卡在以下零件上：

[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)

现在，整个消息保持不变大约1.5个小时，除了xxxxxxx，这是一个不断增加的数字，最近达到了七位数

当我使用PyCharm在我的Windows PC上运行该应用程序时，它运行得非常好

任何帮助都将不胜感激

这是一个有趣的问题，但不知道为什么会发生。你在虚拟机中使用的是什么发行版？@Sarment我使用的是Ubuntu 20.04.2.0 LTS
