Try these commands :
To create virtual env - mkvirtualenv venv_name
To view all virtual env - lsvirtualenv
To activate any virtual env -  workon venv_name
I have virtualenvwrapper-win installed from the command line. When I try to do virtualenv env (env is the name of my virtual environment I'd like to set up) I get this:

'virtualenv' is not recognized as an internal or external command, operable program or batch file

I'm not sure what's wrong. Anyone know how to fix?
Cannot make virtual environment
