Problem when running move_base
Hello guys, I have some problems when I try to run move_base in the navigation package. I hope someone can help me to resolve this problem. My problem is that: "Failed to create the global_planner/GlobalPlanner planner, are you sure it is properly registered and that the containing library is built? Exception: According to the loaded plugin descriptions the class global_planner/GlobalPlanner with base class type nav_core::BaseGlobalPlanner does not exist. Declared types are navfn/NavfnROS"
Have you already verified that it is installed? what does
dpkg -la | grep ros.*global-plannergive you?yes I have installed it but after installed it has an error just like this error above
