Describe the bug I have encountered the error as following root@intel-x86-64:~# ros2 pkg list Traceback (most recent call last): File "/usr/bin/ros2", line 8, in sys.exit(main()) File "/usr/lib/python3.10/site-packages/ros2cli/cli.py", line 67, in main rc = extension.main(parser=parser, args=args) File "/usr/lib/python3.10/site-packages/ros2pkg/command/pkg.py", line 37, in main return extension.main(args=args) File "/usr/lib/python3.10/site-packages/ros2pkg/verb/list.py", line 23, in main for pkg_name in sorted(get_package_names()): File "/usr/lib/python3.10/site-packages/ros2pkg/api/init.py", line 29, in get_package_names return get_packages_with_prefixes().keys() File "/usr/lib/python3.10/site-packages/ament_index_python/packages.py", line 34, in get_packages_with_prefixes return get_resources('packages') File "/usr/lib/python3.10/site-packages/ament_index_python/resources.py", line 63, in get_resources for path in get_search_paths(): File "/usr/lib/python3.10/site-packages/ament_index_python/search_paths.py", line 29, in get_search_paths raise EnvironmentError( OSError: Environment variable 'AMENT_PREFIX_PATH' is not set or empty

To Reproduce

  1. I build the image with bitbake 'ros-image-core' successfully,
  2. I have writed an image file to a storage device on a target board.
  3. login target board and run some ros2 CLI such as ''ros2 pkg list'/ 'ros2 run xx'
  4. error occurs :

The "Build Configuration:" section shown by bitbake at the beginning of the build is very good start.

  1. conf/bblayers.conf ../layers/meta-ros/meta-ros2-foxy \ ..layers/meta-ros/meta-ros2 \ . ./meta-ros/meta-ros-common \ 2 conf/local.conf: IMAGE_INSTALL:append = " \ sros2 \ packagegroup-ros2-demos ros2service examples-rclcpp-minimal-service \ quality-of-service-demo-cpp \ " Expected behavior Can run CLI without error.

source /usr/share/ros_environment/local_setup.bash

This worked for me.
