I installed ros kinetic and uwsim in my Ubuntu 16.04.3 LTS.

As the tutorials in wiki, I run roscore in a terminal, and run rosrun uwsim uwsim in another terminal to run UWSim. The first time I run it just after installation finished, everything is okay.

However, when I closed the window and run it again, it returned uwsim: package not found.

Are there any necessary steps I left out? Or any other possible questions?

Great appreciation if anyone can help.

  • Did you build your catkin work space? I have some problems installing uwsim on my Ubuntu 16.04.3 LTS as well. I tried to dowload an updated version from [Oregon state university mirror](http://ftp.osuosl.org/pub/ros-shadow-fixed/pool/main/r/ros-kinetic-uwsim/) and to compile it with catkin_make but I get errors, some of them related to libxml++. – Mederic Fourmy Apr 26 '18 at 12:48

This question is a bit old but I just had the same issue. In the second terminal where you run rosrun uwsim uwsim, you need to source the uwsim setup.bash file. It should be located at: yourworkspace/devel_isolated/uwsim/setup.bash

source /.../yourworkspace/devel_isolated/uwsim/setup.bash

If you want to avoid typing this all the time you can add the line to your ~/.bashrc file.
