I solved this problem using that:

ln -s [PATH_TO_CARLA]/carla_ros_bridge/ ~/ros/catkin_ws_for_carla/src/
source ~/ros/catkin_ws_for_carla/devel/setup.bash
rosdep update
rosdep install --from-paths ~/ros/catkin_ws_for_carla
cd ~/ros/catkin_ws_for_carla
catkin_make

I used the original carla ros bridge as reference since the carla simulator is missing informations like that :(

https://github.com/laurent-george/carla/tree/dev/add_ros_bridge/carla_ros_bridge

But I'm having another problems and ROS bridge still no work here, good luck

from ros-bridge.

Please follow the instructions in the README.md coming with the ros-bridge. This should work. However, we did not test it with ROS Melodic. We only test with ROS Kinetic.

Hi,

Something similar. I am using Carla 0.8.2 and ROS Lunar Ubuntu 16.04 LTS

When I run the
$ roslaunch carla_ros_bridge client.launch

I get the following error. Please advice.

Wang-Dashan, I solved this problem doing that:

ln -s [PATH_TO_CARLA]/carla_ros_bridge/ ~/ros/catkin_ws_for_carla/src/
source ~/ros/catkin_ws_for_carla/devel/setup.bash
rosdep update
rosdep install --from-paths ~/ros/catkin_ws_for_carla
cd ~/ros/catkin_ws_for_carla
catkin_make
