I am trying to install Django in my windows 7 machine, as a prerequisite, I am installing virtualenvwrapper:
virtualenvwrapper
pip install virtualenvwrapper-win <
pip3 -m venv yourprojectname
Are you trying my command. I got the error like you did with this command I got the problem
but, you can apply the following commands
py -m pip install --user virtualenv py -m virtualenv env
OR
python3 -m pip install --user virtualenv python3 -m virtualenv env
