I can't create a virtual environment with virtualenvwrapper

Question

I try to create a virtual environment with virtualenwrapper-win having it already installed, but when I run the mkvirtualenv name_env command I get the error "mkvirtualenv" is not recognized as an internal or external command, program or executable batch file. What could be causing this?

i expect (name_env) C:\Users\NameUser\Desktop\directory>
