- Exercise 4.4 - Can't build projects anymore

I created the send_goals package from ws_catkin/src with rospy
I added the folders /launch /rviz_config /scripts and created send_goals_client.py and make it executable.
Then I wanted to build the package and that doesn’t even work.

I have no idea what is happening, plz help!

Greetings

The problem is gone, I stopped working on the unit and now everything works again.
I removed the build and the devel folder and also catkin_make does it job again
