--python python3 intializes Python 2

I recently ran the in an Ubuntu 18.04 container, it installed fine but ignored the --python python3 argument. For the record the full command was sudo python3 --production --python python3. Maybe the --production flag overrides the --python flag, I’m not sure. I think it needs to be fixed since Python 2 is EoL’d next year Jan 1 and Frappe and ERPNext both work fine with 3.
