I followed the tutorial:Creating your first ROS 2 package
I entered the following command in my terminal:

ros2 pkg create --build-type ament_python test_pkg_py

I opened package.xmlthat ros2 pkg create automatically generated:

Did I miss any dependecies? ROS environment: Foxy OS: Ubuntu20.04

[ROS2]missing <buildtool_depend>ament_python</buildtool_depend> in package.xml I followed the tutorial:Creat
