SDL2 错误:“无法加载图像 <default.png>"使用 pyinstaller 冻结 kivy 应用程序时

2022-01-15 00:00:00 python kivy pyinstaller sdl-2

问题描述

我无法使用 pyinstaller 生成工作 exe(应用程序的名称是 settings_gui).

I'm unable to produce a working exe with pyinstaller (the name of the app is settings_gui).

运行时错误:(完整日志)

出了什么问题?我检查了 <project_path>/dist/settings_gui/kivy_install/data/glsl/default.png，它就在那里.我觉得很奇怪，但是路径是 SETTING~1，这正常吗?我看过 this thread 建议通过 _MEIPASS<重定向资源/code>，但这无济于事 - 意料之中，因为我不是在单文件模式下构建我的应用程序.

What is going wrong? I checked <project_path>/dist/settings_gui/kivy_install/data/glsl/default.png, it's there. I find it weird however that the path is SETTING~1, is that normal? I've seen this thread which recommends to redirect the resources through _MEIPASS, but this doesn't help - expectedly, since I'm not building my app in one-file-mode.

感谢任何有关如何解决此问题的提示.

Any tip on how to troubleshoot this is appreciated.

编辑:

更多信息:

  • 没有 pyinstaller，应用程序运行得非常好——除非我关闭它或以其他方式停止它；当我这样做时，python 崩溃了.
  • 当我构建我的应用程序时，会打开一个 kivy 窗口并立即崩溃.我总是关闭它并继续构建过程.
  • 我的 .spec 文件
  • 构建日志

解决方案

我通过复制文件解决了这个问题

I managed to fix the issue by copying file

From: [Python]sharesdl2inlibpng16-16.dll
To:   [Dist]<projectName>libpng16-16.dll

那里已经有一个文件实例，但我替换它的那个实例大了大约 20kb(从 198kb 到 213kb).

There was an instance of the file already there but the one I replaced it with was about 20kb larger (from 198kb to 213kb).

重要的是我的应用程序现在可以运行，我没有更改任何其他内容.

The important part is that my app works now and I didn't change anything else.
