[英]Why Kivy App.root instance does not recognize root member method after built by Pyinstaller?
I am making a small Kivy app, it basically works fine in development environment.我正在制作一个小型 Kivy 应用程序,它在开发环境中基本上可以正常工作。 However, it crashed when I launch the built exe file.但是,当我启动构建的 exe 文件时它崩溃了。
build command used:使用的构建命令:
pyinstaller --onefile main.py
Basically, the method store_section() is defined in RootWidget and should be called from on_start() method of App instance.基本上,方法store_section()是在 RootWidget 中定义的,应该从 App 实例的on_start()方法中调用。 And eveything just works well by invoking directly to main.py ( python main.py ).通过直接调用 main.py ( python main.py ),一切都可以很好地工作。 Even Pyinstaller built successfully, I got the following error message when launching the corresponding exe file.即使 Pyinstaller 构建成功,我在启动相应的 exe 文件时也收到以下错误消息。 The error said:错误说:
" AttributeError: 'Widget' object has no attribute 'store_sections' ". “ AttributeError: 'Widget' object 没有属性 'store_sections' ”。

Could someone please help me tackle this error?有人可以帮我解决这个错误吗? Thank you so much.太感谢了。
I don't think the kv
file will be automatically included in the .exe
.我认为kv
文件不会自动包含在.exe
中。 Try running:尝试运行:
pyinstaller --add-data 'ielts.kv';'.' --onefile main.py
