Problem related to $ROSCORE [closed]
Hi,
I have problems regarding the command "$roscore".... I am very much new to Ubuntu and ROS, so i have no idea what i am suppose to do in-order to get rid of this error message i have posted below:
**SUMMARY
NODES No handlers could be found for logger "roslaunch" WARNING: IP address 127.0.1.1 for local hostname 'youbot-laptop' does not appear to match any local IP address (127.0.0.1,192.168.2.2). Your ROS nodes may fail to communicate. Please use ROS_IP to set the correct IP address to use. starting new master (master configured for auto start) Roslaunch got a 'No such file or directory' error while attempting to run: /opt/ros/diamondback/ros/bin/zenmaster --core -p 11311 __log:=/home/youbot/.ros/log/7e9ec426-007e-11e1-99f6-002682c60600/master.log Please make sure that all the executables in this command exist and have executable permission. This is often caused by a bad launch-prefix. [master] process has died**
So, if anyone can please help me in resolving this issue, it would be grateful.... I am in a hurry to show this result as my deadline is nearby......
Thank you in advance...

Maneesh
and yes in addition, i performed these two operations:
$ export ROS_HOSTNAME=localhost $ export ROS_MASTER_URI=http://localhost:11311
and the following error message occurred:
**SUMMARY

but after opening a new terminal window and type $roscore, i get the first error message again.... hope these information are sufficient for you to help me in resolving this issue....thank you
