Unit 2 issue with Launch file for RViz


Can someone help me?

Hi @richard.valenzuela-zavala191 ,

There are two things that you can do to avoid this error:

  1. You can compile only that package using colcon build:
cd ~/ros2_ws
colcon build --packages-select my_box_bot_description
source install/setup.bash
launch my_box_bot_description urdf_visualize.launch.py
  1. You can delete the build, install and log folders and rebuild all packages from scratch:
cd ~/ros2_ws
rm -rf ./build ./install ./log
colcon build
source install/setup.bash
launch my_box_bot_description urdf_visualize.launch.py

Try the first option. If it does not work, then try the second.
If neither works, then let us know.

Regards,
Girish
