turtlesim_node doesn't error out but no window appears
I am trying to learn ROS2 (Foxy) on Windows 10 and am following the official tutorials. When I got to the "2 Start turtlesim" part of the tutorial at https://docs.ros.org/en/foxy/Tutorial..., the command would not error out but the simulator window wouldn't appear either. Running ros2 doctor shows:
<path>\ros2-windows\Lib\site-packages\ros2doctor\api\network.py: 28: UserWarning: Unable to import ifcfg. Use python3 -m pip install ifcfg to install needed package.
[PATH]\ros2-windows\Lib\site-packages\ros2doctor\api\network.py: 67: UserWarning: ERROR: ifcfg module is not imported. Unable to run network check.

I replaced the beginning of the paths with '[PATH]' for security reasons.
