gazebo standalne version cannot be started as usual after installing gazebo ros packages
Hello
I have installed gazebo 1.9 and gazeborospkgs successfully following the instructions in the tutorials both installed from source and I am running ros groovy. And I tested gazebo using this command : rosrun gazebo_ros gazebo , and it run successfully as well. But the problem is when I want to run gazebo standalone with my world file as usual without ros integration as following “gazebo file.world “
Even though there is no other gazebo running I get this error :Exception [Master.cc:50] Unable to start server[Address already in use]. There is probably another Gazebo process running.
Any solutions for this error! Thanks in advance!
