ROS报错记录总结

1.运行roslaunch文件报错：

RLException: Invalid roslaunch XML syntax
详细报错日志：
RLException: Invalid roslaunch XML syntax: not well-formed (invalid token): line 1, column 0
The traceback for the exception was written to the log file

解决办法：rslaunch pkg node.launch (pkg是功能包名，node是可执行程序名)

注意命令与文件程序对应
roslaunch 启动 .launch头文件
rosrun 运行 .py .cpp 程序以及可执行文件

2.运行Rviz报错

symbol lookup error: /opt/ros/noetic/lib/libmoveit_planning_scene_rviz_plugin_core.so.1.1.14: undefined symbol: _ZN4rviz14StringPropertyC1ERK7QStringS3_S3_PNS_8PropertyE

解决办法：将工作空间下的devel和build删掉，重新catkin_make
