file 'my_package_launch_file.launch.py' was not found in the share directory of package 'my_package' which is at '/home/user/ros2_ws/src/install/my_package/share/my_package'
but it exists in
~/ros2_ws/src/my_package/launch
any hint why the build didn’t add the launch File to the package ?
I believe, it is because you might have missed some line(s) in your setup.py file.
Check if you have done the following steps: (specifically step 2 in the below snippet)
Make changes to setup.py file:
------------------------------
Add: import os
Add: from glob import glob
Add to data_files list: (os.path.join('share', package_name), glob('launch/*.launch.py'))
Add to entry_points dict console_scripts:
['python_executable_name = pkg_name.python_executable_name:main']
And make sure your launch.py file is in this format:
Generate Launch File:
---------------------
from launch import LaunchDescription
from launch_ros.actions import Node
def generate_launch_description():
return LaunchDescription([
Node(package="package_name",
executable="python_executable_name",
output="screen"),
])
I believe, these should fix your problem!
