catkin_tools : "Import error: no module named asyncio"

edit

Hi, I have recently installed ROS Melodic on Windows. Initially, I was getting an error that catkin is not a recognized command. So I downloaded catkin_tools from its official documentation. After downloading, I have been getting this error: "Import error: No module named asyncio" whenever I use any catkin command. I searched online and asyncio is a Python 3.3+ command. But the standard installation procedure (given on the ROS website) downloads Python2.7amd64 files. How do I sort this issue

I am running a Windows 10 Home 64-bit machine. Python version: Python 2.7.15 ROS: ROS (1) Melodic (I have downloaded the full desktop version)
