qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""

这个错误信息通常是由于在运行Qt应用程序时缺少了Qt平台插件导致的。根据引用[1]和引用提供的信息,我建议你尝试以下解决方案:
1. 检查你的系统是否安装了Qt的xcb插件。可以通过运行`apt search libqt5xcbqpa`来查看是否已经安装。如果没有安装,可以通过运行`sudo apt-get install libqt5xcbqpa`来安装。
2. 检查你的应用程序的环境变量是否正确设置。确保`LD_LIBRARY_PATH`环境变量包含了Qt的库文件路径。你可以在终端中运行`echo $LD_LIBRARY_PATH`来查看当前的设置。如果没有设置,可以通过在终端中运行`export LD_LIBRARY_PATH=/path/to/qt/lib:$LD_LIBRARY_PATH`来添加。
3. 如果以上解决方案都没有起作用,你可以尝试重新安装Qt或者重新编译你的应用程序。根据引用提供的信息,可能是由于Qt平台插件文件丢失或损坏导致的。重新安装Qt或重新编译应用程序可以解决这个问题。
请注意,以上解决方案仅适用于Ubuntu 18.04下解决Qt出现"qt.qpa.plugin: Could not find the Qt platform plugin 'xcb' in ''"错误的情况。如果你的操作系统或环境不同,请根据具体情况进行调整。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
