    我尝试使用deepin v23 社区版安装运行 PPOCRLabel（https://github.com/PFCCLab/PPOCRLabel.git），发现无法运行，命令行提示

    我很想知道是不是系统的安装的C++库问题，还是我的依赖内容安装出现问题，导致的无法运行。如果能通过修改配置文件应该如何去做，太痛苦了，本菜鸟表示不服但是又拿它没办法，求诸位大佬解答一二。

    sudo apt-get install libxkbcommon-x11-0

    看看你的 QT_QPA_PLATFORM_PLUGIN_PATH环境变量，echo一下，假如是空的话，那就在.bashrc里面加入包含 libqxcb.so的目录 ，可能是你的Python虚拟环境中的 .venv/lib/python3.10/site-packages/cv2/qt/plugins

    你是直接下载的它的二进制还是源码编译的呀

    就是虚拟环境自动下载的libqxcb.so文件

    我尝试让系统的export QT_QPA_PLATFORM_PLUGIN_PATH=.venv/lib/python3.10/site-packages/cv2/qt/plugins

    能够虚拟环境下直接输出环境变量：

    (.venv) Mashiro@Mashiro-PC:/media/Mashiro/inst_47/Project/python/PPOCRLabel$ echo $QT_QPA_PLATFORM_PLUGIN_PATH
/media/Mashiro/inst_47/Project/python/PPOCRLabel/.venv/lib/python3.10/site-packages/cv2/qt/plugin:

    并且libxkbcommon-x11-0已经安装过了，但是依旧提示

    qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/media/Mashiro/inst_47/Project/python/PPOCRLabel/.venv/lib/python3.10/site-packages/cv2/qt/plugins" 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: xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl.

    我想是不是因为缺少了哪些库导致cv2的载入不全？
