本文介绍了在使用PySide6时遇到Qt平台插件xcb加载错误的处理方法，包括开启QT插件调试日志、查看具体错误信息以及安装缺失的libxcb-cursor库。

报错

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimalegl, vkkhrdisplay, linuxfb, eglfs, vnc, offscreen, xcb, wayland-egl, minimal, wayland.

pyside6开发程序运行报错处理方法：

1.添加环境变量打开QT插件调试日志输出

os.environ["QT_DEBUG_PLUGINS"] = "1"

2.查看具体报错

qt.core.plugin.factoryloader: Got keys from plugin meta data QList("wayland")

已放弃

3.安装对应插件的开发库
