Which python-ros2-package should I install if I want to use "ros2" command like, "ros2 run demo_nodes_cpp talker"?

Hi guys,
I am trying using ros-foxy on Windows, as following the ROS2 tutorial.
At the beginning, I need to run "ros2 run demo_nodes_cpp talker", but I don't know which python-ros2-package I should install in this list -- https://robostack.github.io/foxy.html.
I want to know whether there is a list for ros2-command and corresponding python-ros2-package?
By the way, does "ros2 run" correspond to ros-foxy-ros-base or ros-foxy-ros-core?

Your answer and guide will be appreciated!

Hi @songyuc, many thanks for trying ROS2 Foxy with RoboStack!
You will need to install ros-foxy-demo-nodes-cpp, however as you can see from the list it's not yet available for Windows. If you want to use this package, consider adding it as described in https://github.com/RoboStack/ros-noetic/blob/master/CONTRIBUTING.md#adding-new-packages-via-pull-requests with an example found in RoboStack/ros-noetic#44 (it would be a adding a single line to https://github.com/RoboStack/ros-foxy/blob/master/vinca_win.yaml in this case).

Regarding the second question (ros2 run package) I am unfortunately not sure.
