Hi, all

I don't know how to use nav_view package in Electric. I download the
package from diamondback and compile it in Electric. When I roslaunch my
pkg, I get the error:
*ERROR: cannot launch node of type [nav_view/nav_view]: cannot locate node
of type [nav_view] in package [nav_view]*

Anyone knows how to solve this problem? Thanks.
