PySide6 pyside6-deploy 命令 Linux 部署

PySide6 Linux 部署

写在前边

Qt是非常强大的跨平台框架,Qt for Python(PySide/PyQt)作为Qt给Python提供的接口，理论上也可以部署到任意平台上边。这篇文章就是将PySide6``Python实现的代码部署到Linux环境。 其部署出的文件是一个.bin文件。

pyside6-deploy 是 Qt for Python 的部署工具，基于Nuitka

Ccache 是一个编译器缓存。它通过缓存以前的编译并检测何时再次执行相同的编译来加快重新编译 。

--------This simple script shows a label with changing "Hello World" messages.
It can be used directly as a script, but we use it also to automatically
test PyInstaller or Nuitka. See testing/wheel_tester.py .When compiled with Nuitka or used with PyInstaller, it automatically
stops its execution after 2 seconds.
