ROS_MASTER_URI is not defined in the environment. Either type the following or (preferrably) add this to your ~/.bashrc file in order set up your local machine as a ROS master:

export ROS_MASTER_URI=http://localhost:11311

then, type ‘roscore’ in another shell to actually launch the master program

問題原因

沒有新增ROS_MASTER_URI變數
