ncu-ui赢得了运行：无法加载QT Platform插件“ XCB”在“”即使发现

Question

我正在尝试在CentOS 7 Linux系统（使用NCU-UI 2022.1）上运行ncu-ui profiler gui，无论是root还是常规用户。我遇到了错误：

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: xcb.

我已经安装了一堆XCB库，问题并没有消失。我应该怎么办？

Answer 1

就我而言，它缺少libxcb-xinput。因此，

sudo apt-get install libxcb-xinput-dev

解决了问题。

Answer 2

tl; dr：install libxkbcommon-x11。

您注意错误消息的结束

Application could not be initialized!
    This is likely due to missing Qt platform dependencies.
    For a list of dependencies, please refer to https://doc.qt.io/qt-5/linux-requirements.html
    To view missing libraries, set QT_DEBUG_PLUGINS=1 and re-run the application.

如果 运行该操作时：

他们的关键行是：

libxkbcommon-x11.so.0: cannot open shared object file: No such file or directory

因此，安装libxkbcommon-x11（也许libxkbcommon均为良好的措施）。那应该做到。但是 - 如果您收到有关丢失文件的不同错误消息，则需要弄清楚它属于哪个软件包。
