我非常接近（希望）执行我使用 pyinstaller 构建的.exe。 我相信这个问题与 sdl2 或 associated.dll(s) 有关。 根据本指南，我需要在 .spec 文件中指向 sdl2.dll

“前面的示例使用了例如 *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins + gstreamer.dep_bins)]，以使 PyInstaller 添加这些依赖项使用的所有 dll。如果 kivy 没有使用轮子安装方法这些命令将不起作用，例如 kivy_deps.sdl2 将无法导入。相反，必须找到这些 dll 的位置并以与示例类似的方式手动将它们传递给 Tree class。

这个规范文件是从这里复制的，而且我不确定它的大部分内容。 只是试图让 .exe 启动并运行，以便我可以演示应用程序。

Answer 1

我将以下内容添加到 .spec 文件中：

from kivy_deps import glew, sdl2
Tree(<'path to main.py'>),
*[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],

这为我解决了 sdl2 问题。 我还在使用早期的英特尔高清显卡，它遇到了一些问题：OpenGL 和识别版本 2.0+stackoverflow 上 sdl2 问题的一些解决方案讨论了更改 KIVY BACKEND 的环境变量而不是 angle_sdl2 - 我也做了这种变化。
