[rosrun] Couldn't find executable named serial_node.py below /opt/ros/noetic/share/rosserial_python
I try to connect Arduino to ros master noetic. I already install the following packages
sudo apt install ros-noetic-rosserial*
sudo pip install pyserial
after that I run the command
rosrun rosserial_python serial_node.py /dev/ttyACM0
and get the the following error
[rosrun] Couldn't find executable named serial_node.py below /opt/ros/noetic/share/rosserial_python
