While running ROS node it's showing the following output.

parth@parth007:~/catkinws/src/pkgrosbasics/scripts$ cd ~/catkinws parth@parth007:~/catkinws$ rosrun pkgrosbasics nodehelloros.py [rospack] Error: package 'pkgrosbasics' not found parth@parth007:~/catkinws$ cd ~/catkinws/src parth@parth007:~/catkinws/src$ rosrun pkgrosbasics nodehelloros.py [rospack] Error: package 'pkgrosbasics' not found

roscore tested in both catkin_ws and src dir separately

Workspace cmd

cd ~/catkin_ws catkin build.

Installed pkgs

Catkin Tools sudo apt-get install ros-melodic-catkin python-catkin-tools std_msg package
sudo apt install ros-melodic-std-msgs turtlesim
sudo apt-get install ros-melodic-ros-tutorials

All cmd for workspace and pkg creation ran successfully only, ros node output not getting.

Thanks in advance
