Tracetools_launch not found

Course Support ROS Basics In 5 Days (Python)

I am trying to use the tracetools_launch package that I was using from chapter 6 of the course (multithreading) but I received this error ModuleNotFoundError: No module named 'tracetools_launch'

How should I fix this error?

Hi @jeffrey.jahja7, if tracetools_launch is a package provided by the course, you should be able to fix this by simply trying your command in a different terminal. The sourcing might be mixed up in the terminal you are using.

If this is a package you created or imported into your workspace, it should be found by sourcing it, most likely in ~/catkin_ws:

source ~/catkin_ws/devel/setup.bash

Thank you @rodrigo55 !
