Hello this error indicates that something is wrong with your source command. Please check exactly where they told you to source using the command:
source intsall/setup.bash
Try to do in the directory ~/ros2_ws and in ~/ros2_ws/src

[bayodesegun]

The right source command is:

# You need to run it from `ros2_ws`
cd ~/ros2_ws
source install/setup.bash

If it does not work after source, double-check that you have the right setup in setup.py.

Hi @albin.magnu ,

The error is straight-forward and clearly states that the specified launch file could not be found within the install directory of the package.

This is because, I believe, you have forgotten to add the launch file path(s) in your setup.py file.

You need to add the following line in your setup.py file inside the data_files parameter inside the setup() function.

(os.path.join('share', package_name), glob('launch/*.launch.py'))

That should fix your problem. Let me know if you still have issues.

Regards,
Girish
