roscore error, ROS_MASTER_URI
Hello! Everyone. I have encountered an roscore error. When I run roscore, the screenshot is presented as follows.
I only open a terminal, and thus I am sure I do not run another roscore. Besides, when I run roslaunch, it does not print an error, but all wait. I guess whether the ROS_MASTER_URT set is right or not. Thanks in advance and best regards. The error is further presented as bleow.
roscore cannot run as another roscore/master is already running.
Please kill other roscore/master processes before relaunching.
The ROS_MASTER_URI is http://yxg-Inspiron-5443:11311/
The traceback for the exception was written to the log file
