"catkin build" not working in ros noetic via docker

Question

I am using ros noetic via docker on windows.

The command "catkin build" returns "bash: catkin: command not found".

I tried:

• sudo pip3 install git+https://github.com/catkin/catkin_tools.git

• sudo apt-get install python3-catkin-tools

nothing worked.

Can someone help ?

You are missing the source part for the system to know what catkin is. Try doing source /opt/ros/noetic/setup.bash and the running the command catkin build in your workspace.
