当我运行R命令时，我得到以下错误：

qt.qpa.xcb: could not connect to display 
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: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

我已经看了所有其他的回应，并“解决”了这个问题的问题，但他们没有为我解决这个问题，我不知道如何解决这个问题，我自己为我的特定设备。
有没有人可以教我如何解决这个问题，而不使用复杂的语言？我不知道任何命令来访问的东西，所以它使尝试使用在线答案非常困难。

有没有人可以告诉我重新安装插件需要使用的命令？我还没有看到任何人在任何地方发布。

sudo apt install libxcb-util1

帮我修正了这个错误。
要查看缺少哪些符号，请运行前缀为QT_DEBUG_PLUGINS=1的应用。

缺少什么库可能会有所不同，但找到哪一个（S）可以不依赖于猜测。
首先，让我们注意到，当使用预构建的Qt包时会发生这种问题，而这些包并不随您的发行版一起提供（通常会正确地获得这种依赖关系）。例如，当使用pip（例如pip install PySide6）安装Qt for python时，就会发生这种情况，因为该包确实附带了自己的库副本。
找出xcb平台插件的位置：

$ find env/lib/python3.9/site-packages/PySide6 -name "*xcb*"
env/lib/python3.9/site-packages/PySide6/Qt/metatypes/qt6xcbqpaprivate_relwithdebinfo_metatypes.json
env/lib/python3.9/site-packages/PySide6/Qt/plugins/xcbglintegrations
env/lib/python3.9/site-packages/PySide6/Qt/plugins/xcbglintegrations/libqxcb-glx-integration.so
env/lib/python3.9/site-packages/PySide6/Qt/plugins/xcbglintegrations/libqxcb-egl-integration.so
env/lib/python3.9/site-packages/PySide6/Qt/plugins/platforms/libqxcb.so

字符串
最后一行看起来确实像一个“平台插件”，我们可以看看它缺少了哪些库：

$ ldd env/lib/python3.9/site-packages/PySide6/Qt/plugins/platforms/libqxcb.so |grep "not found"
        libxcb-cursor.so.0 => not found
        libxcb-cursor.so.0 => not found

型
这样我们就有了库名称，并且可以轻松地安装匹配的包（在基于Debian的发行版上为libxcb-cursor0）。
