There is a very hacky method that I have successfully used before. This may not work in many cases. So, You source a terminal with ROS environment variables and run roscore. In another terminal first source ros and then python3 environment variables. now run your python3 node here. This is possible coz of the amazing backporting capabilities of python. Again this may not work in every case. So its your luck

If you want to use a different Python version, you'll probably have to install ROS from sources, all the while keeping an eye on the commands to make sure you're using the correct Python interpreter binary.
There have been Q&As about this, I recommend using google (with
site:answers.ros.org).
