問題記錄

1. Q: 找不到庫

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, webgl, xcb.

A:

• 在~/.bashrc中添加如下內容後， source ~/.bashrc。可查看詳細運行結果

  export QT_DEBUG_PLUGINS=1
  export PATH="/home/xxx/Qt5.9.2/Tools/QtCreator/bin:$PATH"
  export PATH="/home/xxx/Qt5.9.2/5.9.2/gcc_64/bin:$PATH"
  

• 運行腳本查看到底因爲什麼原因。

  Cannot load library ..PyQt5/Qt/plugins/platforms/libqxcb.so: (libxcb-xinerama.so.0: cannot open shared object file: No such file or directory)
  

  上述解決辦法：

  sudo apt-get install libxcb-xinerama0
