No support for python -m venv application

[ronflima]

There is no support for python -m venv virtual manager, which is default in python 3 projects. Since python 2 will end support in 2020, it is a good idea to have support for default python 3´s virtual environment manager instead of virtualenv application.

whats the work around for this? 🤔

I'd expect this commit (392e28d) to fallback to "-m venv" use if virtualenv isn't installed:

Are people saying there is not correctly functioning support with the latest version (this commit is 8 months old, from Sept 2019) - a quick check suggests it works fine?

                        "-m" "venv" venv-dir)
