As the title mentioned, I'm trying to use rqt_graph to observe my nodes. However, it showed
rvl224@eervl224:~/brian2lee/gazebo/forklift_test$ rosrun rqt_graph rqt_graph [rospack] Error: package 'rqt_graph' not found rvl224@eervl224:~/brian2lee/gazebo/forklift_test$ rqt_graph rqt_graph：無此指令
(The chinese part is rqt_graph: command not found) But there literally rqt-gui 0.5.3 & rqt-gui-py 0.5.3 in my pip list. Have no idea how to solve it. Just in case it's problem like package conflict here's the pip list.

Some ideas what to check (or provide further information about):
source /opt/ros/noetic/setup.bash for noetic)roscore running? (if not run: roscore)rqt_gui (run: rqt or rosrun rqt_gui rqt_gui ) to check if rqt_graph is available there?ros-%YOUR_ROS_DISTRO%-rqt-common-plugins package as well (as official installation guideline requests)? Because rqt_graph is part of this package (see here).
