That it's not possible? venv is literally just a module of the standard distribution. And while virtualenv can do a few more things (hence why it remains as an independent project), installing new pythons is not something it can do. Virtualenv and venv can only create environments for previously installed python (especially venv as you create environments via the python you want to create an env for, it doesn't support creating an env on behalf of a different python than the one it's invoked through).
