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, xcb.Aborted (core dumped)解答 通过export QT_DEBUG_PLUGINS1查看问题的具体显示输出问题的内容形式如下

exit这里参考非常宝藏的社区解决方法 在宿主机中运行
docker run -it -v /tmp/.X11-unix/:/tmp/.X11-unix/:rw --envDISPLAY --name ros2_container osrf/ros:humble-desktop-full解释
-v /tmp/.X11-unix/:/tmp/.X11-unix/:rw
-v 选项允许 Docker 将一个卷挂载到容器上这样容器就能访问宿主机文件系统上的目录
/tmp/.X11-unix/ 是宿主机上由 X 服务器用于显示的一个目录
:/tmp/.X11-unix/ 是容器中挂载卷的位置与宿主机上的目录相同
:rw 部分允许对卷进行读写访问这对显示内容是必要的。--envDISPLAY
这个参数将宿主机的 DISPLAY 环境变量传递给容器。
DISPLAY 变量以启用可视化这里我重点排查了一下貌似是因为之前通过
docker image pull osrf/ros:humble-desktop-full
#拉取的镜像有些东西没有拉取成功 导致RVIZ2始终运行不成功使得我又重新构建了一个container_ros2 ! docker run -it --name ros2_container osrf/ros:humble-desktop-full 接下来报错问题

#执行
export QT_DEBUG_PLUGINS1 // 用来输出QT报错的完整信息
再次在docker中运行rviz2的节点
ros2 run rviz2 rviz2 #查看完整报错内容
echo $DISPLAY 判断是不是利用宿主机显示rviz2出现的问题
本地终端输入
sudo xhost 然后按下回车
输入密码
出现下图
再在docker中
ros2 run rviz2 rviz2成功展示界面 这里要注意你rviz2启动的container需要一致 例如我这里的docker image 存在多种 但是这里只有ros2_container成功拉取了rviz2所以 其他的仍然存在rviz2显示问题(那就重新下载一下我的SDK相关包和依赖库)
删除 Docker 镜像和容器
我是个眼里不容沙子的人没用的docker container需要选择删除 列出所有镜像以获取镜像的 ID docker images -a 明确删除哪个镜像 docker rmi your-image-id 操作如下 sudo systemctl start docker
sudo systemctl enable dockerdocker images -adocker rmi d2c94e258dcb
docker iamges -a删除 Docker 容器
#停止所有正在运行的容器
docker ps -a //列出 所有容器 停止和未停止
docker ps //列出所有正在运行的容器删除多个容器
docker rm $(docker ps -a -q)
#用来删除所有停止的容器一般情况下可以将线程数设置为CPU核心数的2倍
Linux服务器下查看系统CPU个数、核心数、(make编译最大的)线程数
# 查看CPU
lscpu #查看cpu的所有信息

cat /proc/cpuinfo| grep processor| wc -l
grep physical id /proc/cpuinfo 查看核心数量 每个物理CPU含有的核心个数。

首先在安装完成fastlio2需要的依赖库后
mkdir -p /FastLIO2_ws/src cd /FastLIO2_ws/src
git clone --recursive https://github.com/liangheming/FASTLIO2_ROS2.git
cd .. #这里colcon 需要在src目录下
colcon build --symlink-install. ./install/setup.bash #激活安装的fastlio2 node问题:rviz2不能播放db3的rosbag数据 新开启一个终端
docker exec -it rose_container /bin/bash
source /opt/ros/humble/setup.bash
source /FastLIO2_ws/install/setup.bash
ros2 bag play FastLIO_ROS2_Data问题解决 需要在colcon build --symlink-install build fastlio2之前 一定要在colcon build --symlink-install 之前source /ws_livox/install/setup.bash!!! source /ws_livox/install/setup.bash ###!!!!!!cd /FastLIO2_ws/colcon build --symlink-install ## !!!!. ./install/setup.bash ##!!!! 然后在按照上面的方法开启新的终端 ros2 bag play ors_bag_dir 最终能够成功播放数据集。 结果展示
