Frequently Asked Questions

I still see old config/launch.py (yaml/py) files even after I edited them in my packages?

In ROS2, the config (yaml) and launch.py (python) files are copied to the install directory of your workspace during the install phase of your build process. You can verify this by looking at the install() functions inside the CmakeLists.txt file of your package. So, if you edit the config (yaml) or launch.py (python) files, you need to run the colcon build command to copy the modified files to the install directory.
