@PANTUM_61 Did you set up your workspace properly. Can you ensure your executable exists in the build folder after performing a catkin_make? To be more clear the complete command is: rosrun my_package my_pakage_node

I do not know if I understood you properly. To have a functional enviroment you first need to have a workspace, then, inside that workspace a src folder in which you place your package folders and then from the root of the workspace you need to source your environment and call the catkin_make to compile all your packages. Once the compilation process you can use the rosrun to start a node. catkin_ws is not a package name folder but the folder in which your workspace was set up. Can yoy share your folders structure, I think you have a bad one.
