SDL2错误:“无法加载图像< default.png>".使用pyinstaller冻结kivy应用程序时 [英] SDL2 Error: "Unable to load image <default.png>" when freezing kivy application using pyinstaller

问题描述

我无法使用pyinstaller生成可运行的exe(应用程序的名称为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，它在那里.我发现路径为SETTING~1很奇怪，这正常吗?我见过此线程，它建议通过_MEIPASS重定向资源，但是这无济于事-可能是预期的，因为我不是以单文件模式构建应用程序.

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.

任何有关如何解决此问题的技巧都将受到赞赏.

Any tip on how to troubleshoot this is appreciated.

修改:

更多信息:

• 没有pyinstaller，该应用程序运行得很好-除了关闭或以其他方式停止该应用程序外；当我这样做时，python崩溃了.
• 构建应用程序时，会打开一个奇异的窗口，并立即崩溃.我总是关闭它，然后继续构建过程.
• 我的.spec文件
• 构建日志

• Without pyinstaller, the app runs perfectly fine - except for when I close it or stop it otherwise; when I do that, python crashes.
• When I build my app, a kivy window opens and crashes immediately. I always close it and the build process continues.
• My .spec file
• Logs of the build

推荐答案

我设法通过复制文件来解决此问题

I managed to fix the issue by copying file

From: [Python]\share\sdl2\bin\libpng16-16.dll
To:   [Dist]\<projectName>\libpng16-16.dll

已经有一个文件实例，但是我替换为该文件的实例大约大了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正常工作了，而我没有做任何其他更改.

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