Hello there I am trying to install mavros ROS package, following this tutorial: https://dev.px4.io/en/ros/mavros_inst...

Everything went well till the 'catkin build' expression. I get the following error message:

Errors << catkin:cmake /home/user/catkin_ws/logs/catkin/build.cmake.000.log CMake Error at /home/user/catkin_ws/src/catkin/cmake/empy.cmake:29 (message): Unable to find either executable 'empy' or Python module 'em'... try installing the package 'python-empy' Call Stack (most recent call first): cmake/all.cmake:159 (include) CMakeLists.txt:8 (include)

And I have no clue how to solve it. I tried to install the 'python-empy' package but nothing changes.

Can anybody help me?

Thanks so much.

This may be a bit too late, but you could try installing the "python-empy" package using

sudo apt install python-empy

and the rerun catkin build. I have noticed that sometimes if on your system if you have not run the rosdep install step correctly or it did not complete for whatever reason, all these dependencies rear their head when running catkin build
