I installed fuerte on ubuntu12.04,when I begin to run roscore,it gets
asctec@asctec-mastermind:~/fuerte_workspace/sandbox/beginner_tutorials$ roscore

Invalid <param> tag: Cannot load command parameter [rosversion]: command [rosversion ros] returned with code [1].
Param xml is <param command="rosversion ros" name="rosversion"/>
what would cause this error?
This is the same problem as: http://answers.ros.org/question/20780...
They are different problem. In fact I have pip uninstall packages in /usr/local/lib/python2.7/dist-packages and you can see my rospkg is now in /usr/lib/python2.7/dist-packages.
