Hi, I have a problem.

I follow the instruction but I got error: PackageNotFoundError: "package ‘nav2_lifecycle_manage’ not found.

I tried to add nav2_lifecycle_manage in package.xml but it does not work.

Please, check and help me.
Thanks.

Hi @NguyenDuyDuc ,

You actually have a typo error there. You have typed:

nav2_lifecycle_manage

instead of

nav2_lifecycle_manager

You missed the ‘r’ at the end.

       Node(
            package='nav2_lifecycle_manage',   # <--- you missed 'r' here
            executable='lifecycle_manager', 
            name='lifecycle_manager_mapper', 
            output='screen', 
            parameters=[
                {'use_sim_time': True},
                {'autostart': True},
                {'node_names': ['map_server']}
            ], 
        ),
