由于窗口问题，Kivy 应用程序在使用 pyinstaller 打包后崩溃

Question

我正在尝试使用 Pyinstaller 打包我的 kivy 项目，但它崩溃并吐出这个

我没有创建自己的规范文件，我选择通过命令行传递所需的参数来创建任何建议？

这是pyinstaller生成的spec文件

Answer 1

如果您没有创建 spec 文件，您仍然需要将 here 的依赖项打包到 Collect() 中。

正如pyinstaller的docs中提到的：

您可以在 pyinstaller 命令行上提供其他文件。

这意味着您可以使用--add-data，或者您可以将规范转储到某处并使用--specpath 手动编辑它。 Here 是 Collect() 基本上用来打包东西的。

编辑： 是的，你肯定错过了部门。看kivy的规格。

如果您选择--add-data，则应检查其中的kivy.deps 文件夹和__init__()s，因为它们会告诉您要查找的路径。但是手动编辑规范更省时。
