Question

当我运行move_base.launch来实现导航时，我遇到了问题。终端中的错误信息是：

[move_base-4] process has died [pid 3825, exit code -11, cmd /opt/ros/indigo/lib/move_base/move_base __name:=move_base __log:=/home/youjian/.ros/log/b66363a2-96cf-11e6-9e46-e4f89cf5c788/move_base-4.log].
log file: /home/youjian/.ros/log/b66363a2-96cf-11e6-9e46-e4f89cf5c788/move_base-4*.log

我没找到move_base-4.log，但我在master.log找到错误信息，错误信息是：

[rosmaster.threadpool][**ERROR**] 2016-10-20 22:16:04,075: Traceback (most recent call last):

实际上，我之前设法运行了move_base.launch，但机器人被奇怪地导航了，所以我想让move_base节点打印cmd_vel信息。由于我无法在/ opt / ros / indigo中找到move_base.cpp，我从Github复制了move_base包并修改了包，然后在catkin_ws中catkin_make。但是，我没有成功。所以我在catkin_ws中删除了与move_base相关的所有文件，结果是我无法再运行move_base.launch并不断报告上面的错误。

我已经尝试重新安装ros-indigo-move-base，但它没有用。有人能给我一些帮助或建议吗？我是否需要重新安装ROS？＆gt; ...＆lt;

提前感谢！
