ERROR: cannot launch node of type : can't locate node in package
I have installed Ubuntu 18 04 and ROS melodic. I have installed moveit using these instructions: https://ros-planning.github.io/moveit...
Te section i have linked instructs the following:
Open two shells. In the first shell start RViz and wait for everything to finish loading:
roslaunch panda_moveit_config demo.launch
In the second shell, run the launch file:
roslaunch moveit_tutorials move_group_interface_tutorial.launch
The second instruction failed with:
ERROR: cannot launch node of type [moveit_tutorials/move_group_interface_tutorial]: can't locate node [move_group_interface_tutorial] in package [moveit_tutorials]
If i do :
rosrun moveit_tutorials
and tab for autocomplete i don't see the 'move_group_interface_tutorial node'.
I get:
build_locally.sh collision_scene_example.py move_group_python_interface_tutorial.py
I ran:
locate move_group_interface_tutorial
here is the output:

I have 2 workspaces. I created this workspace specifically for moveit!.
here is the text i ahve added to my .bashrc

I ran locate
I have a similar constellation: ROS Melodic and Ubuntu 18.04 and trying to run a YDLidar X2. When I do the command: "roslaunch ydlidar_ros_driver X2.launch" I get these error message.
Therefore I did "roslaunch-logs": roslaunch][INFO] 2020-12-10 11:21:10,246: Checking log directory for disk usage. This may take a while. Press Ctrl-C to interrupt [roslaunch][INFO] 2020-12-10 11:21:10,261: Done checking log file disk usage. Usage is <1GB.

That is not the whole logfile, but I real don't know where the ERROR occures from. [roslaunch][INFO] 2020-12-10 11:21:14,362: ... successfully launched [rosout-1] [roslaunch][INFO] 2020-12-10 11:21:14,364: load_parameters starting ...

Did anyone has an idea how to find a solution ? I real appreciate your answers.
