I need to use rqt_aciton tool to monitor an action communication but when I run rqt_action I got this error message. I've tried sudo apt-get install ros-noetic-rqt-action it told me that ros-noetic-rqt-action is already the newest version (0.4.9-1focal.20230215.222247). Also tried source /opt/ros/noetic/setup.bash, it didn't work neither. I even downloaded the source code in github and compiled it, source it, problem was still there. Besides, rosrun actionlib axclient.py was also dead.

  • Try to open `rqt` and check the menu bar if this plugin is available. – Darkproduct Mar 20 '23 at 13:58

    I found that script axclient.py, and some other scripts were in the actionlib_tools package, so I installed `actionlib_tools` and ran `rosrun actionlib_tools axclient.py`, problem solved. – SmileJay Mar 22 '23 at 06:12
