I made it though almost the entire tutorial but when I go to try out the talker I get this response

logan@logan-Ubunto:~/dev_ws$ source install/setup.bash
logan@logan-Ubunto:~/dev_ws$ ros2 launch my_package talker.launch.py
file ‘talker.launch.py’ was not found in the share directory of package ‘my_package’ which is at ‘/home/logan/dev_ws/install/my_package/share/my_package’

when i go look at the my_package directory this is the contents

logan@logan-Ubunto:~/dev_ws/install/my_package/share/my_package$ ls
cmake local_setup.bash local_setup.zsh package.ps1 package.zsh
environment local_setup.dsv package.bash package.sh
hook local_setup.sh package.dsv package.xml

i don’t really understand what is the issues here so any advice or thoughts would be much appreciated

I have the same problem, please let me know if you find a solution.

I am using ROS 2 Humble on Ubuntu 22.04 though

Hmm I just ran through the tutorial myself on humble and it seems to work ok.
Some things to double check:

  • You added the new files in the correct location
  • You added the install() function to CMakeLists.txt
  • You rebuild with colcon from the root of the workspace

If you check those and are still stuck, post your commands from colcon onwards :slight_smile:

Yeah, I messed up the directories, it works now.
