ROS报错：IOError: [Errno 13] Permission denied: '/home/zn/.ros/log/robotiq2FGripper.log'

运行Robotiq控制驱动节点报错

rosrun robotiq_2f_gripper_control Robotiq2FGripperRtuNode.py / dev / ttyUSB0

IOError: [Errno 13] Permission denied: '/home/zn/.ros/log/robotiq2FGripper.log'

解决方案

这个问题是由于该路径下ros文件权限造成的。

输入以下命令修改权限：

sudo chmod 777 -R ~/.ros/

修改完成后再次输入roscore就ok了
