roslaunch not working during tutorial (rosversion?)
When doing the roslaunch tutorial I was suppose to use this command:
roslaunch beginner_tutorials turtlemimic.launch
I get an error which prevents me from continuing the tutorial and I've set the ROS_PACKAGE_PATH to include the catkin_ws. (also am I suppose to add the path of the catkin or the rospackage). Anyways the error I get is:
WARNING: unable to configure logging. No log files will be generated
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.
Invalid <param> tag: Cannot load command parameter [rosversion]: command [rosversion roslaunch] returned with code [1].
Param xml is <param command="rosversion roslaunch" name="rosversion"/>
Any help on this would be great as I am trying to learn ROS for the AUV we are making and I can't find anything related to this online.
Thanks
EDIT: Using ROS Hydro on Ubuntu 12.04
Can you run `rosversion roslaunch` ? Is this an installation from debs or from source?
I have the same error when following the tutorial. When I run 'rosversion roslaunch' the version is 1.9.50.
