cannot find mavlink_sitl_gazebo

[atieh-sahraei]

Hi, My Setup information is as follow: Mavros: [Installed by, install_geographiclib_datasets.sh] ROS: [melodic] Gazebo: [9] Ubuntu: [18.04] and the installation did not have any issue and when running " make px4_sitl_default gazebo" the gazebo runs without error. I also set the paths. However, recently when I want to run the sitl with mavros "roslaunch px4 mavros_posix_sitl.launch" I get the following error: (It is strange because the day before I could run the launch file but now it gives error) I am following this tutorial: [(https://gaas.gitbook.io/guide/software-realization-build-your-own-autonomous-drone/build-your-own-autonomous-drone-e01-offboard-control-and-gazebo-simulation)]

Resource not found: The following package was not found in : mavlink_sitl_gazebo ROS path [0]=/opt/ros/melodic/share/ros ROS path [1]=/home/name/catkin_ws/src/mavros/test_mavros ROS path [2]=/home/name/catkin_ws/src/Firmware ROS path [3]=/home/name/catkin_ws/src/mavros/mavros_extras ROS path [4]=/home/name/catkin_ws/src/mavros/mavros ROS path [5]=/home/name/catkin_ws/src/mavros/mavros_msgs ROS path [6]=/home/name/catkin_ws/src/mavros/libmavconn ROS path [7]=/home/name/catkin_ws/src/beginner_tutorials ROS path [8]=/opt/ros/melodic/share The traceback for the exception was written to the log file

This is the launch file: `<?xml version="1.0"?>

It seems like your GAZEBO_PLUGIN_PATH is not set correctly

Your package is not found in the path of ROS packages. It seems have not sourced your current workspace in your terminal. Build your packages again and source your workspace again after building it.

You should check your ~/.bashrc, and make sure GAZEBO_PLUGIN_PATH is set correctly.
