同时启动rqt也存在报错

系统是unbuntu18.04 Jetson Xaiver NX开发板在此之前只安装过miniforge和安装搜狗输入法，装完ros后没有办法启动rviz和rqt，通过 locate libqxcb 发现

/media/nvidia/21936f55-9c2d-4d1a-9b0a-c27dcd577a97/usr/lib/aarch64-linux-gnu/qt5/plugins/platforms/libqxcb.so
/opt/MVS/bin/platforms/libqxcb.so
/usr/lib/aarch64-linux-gnu/qt5/plugins/platforms/libqxcb.so

直接在 ~/.bashrc中添加

export QT_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins/:$QT_PLUGIN_PATH

再运行rviz会报错

但是另外的板子也是5.9.5的版本，真的不知道咋子搞了，求助！

这个问题看起来与Qt库版本不匹配有关。你的Jetson Xavier NX上的Qt版本为5.9.5，而ROS Melodic可能需要一个不同版本的Qt。以下是一些可能的解决方法：

更新ROS依赖的Qt版本：ROS Melodic使用的Qt版本可能不与Jetson Xavier NX上的Qt版本匹配。你可以尝试更新ROS依赖的Qt版本以匹配你的系统上的Qt版本。这可能需要一些手动编译和安装。
使用docker容器：ROS官方维护了Docker容器，这些容器可以在不同的系统上运行，而不会受到主机系统的Qt版本的影响。你可以尝试在Jetson Xavier NX上运行ROS容器，这将隔离ROS环境，避免与系统Qt版本的冲突。
查看ROS Melodic的系统要求：确保你的Jetson Xavier NX系统符合ROS Melodic的系统要求。有时，特定版本的ROS可能需要特定版本的操作系统或软件库，确保你的系统满足这些要求。
升级ROS版本：如果可能的话，考虑升级到ROS Noetic或其他更高版本，看看是否有更好的兼容性。
查找并删除不兼容的Qt库：查找并删除Jetson Xavier NX上的Qt库，确保不会与ROS Melodic的Qt库发生冲突。但请谨慎操作，以免影响其他应用程序。
查看其他用户的解决方案：在ROS社区或Jetson Xavier NX的用户社区中，可能有其他用户遇到了类似的问题并提供了解决方案。查看相关讨论论坛或社交媒体组可能会有所帮助。

请记住在尝试上述解决方案之前备份重要数据，并小心操作，以避免对系统造成不可逆的损害。根据你的需求和系统设置，选择最适合你的解决方案。
