I'm using ROS noetic on ubuntu 20.04 lt via WSL2. I'm trying to access the package through catkin build, I keep getting an error I'm new to ROS (beginner). So, I'm learning a tutorial from youtube. I've installed their git repository and following their steps. This is the command I input

catkin build ros_package_template

and I get this output

catkin: command not found

It might make sense to ask "them" what is wrong then. "They" might know.

Have you run source /opt/ros/noetic/setup.bash in your current terminal window to update your environment variables to include the installed ROS package paths?

Section 1.5 of the Ubuntu ROS installation instructions has some more guidance about setting up your environment, such as adding the source command to your .bashrc file so it runs automatically when you start a new terminal.

catkin_tools is installed in the regular system locations, so shouldn't need sourceing any setup.bash file.

@pranav_jain: what is the output of dpkg -l | grep catkin-tools?
