Es necesario usar un viartualenv para poder manejar varios proyectos con diferentes versiones de paquetes como por ejemplo usar python7
en un proyecto de django o tener otro proyecto de django con python3 

1 - Es necesario instalar pip 
https://pip.pypa.io/en/stable/installing/

2 - Se instala en virtualenv. Para crear un proyecto solo es necesario ejecutar el comando virtualenv [paht name] si se quiere usar
    una versión de python en especial solo se necesita usar el comando virtualenv -p /usr/bin/python2.7 [path name]
    después de esto se crea el proyecto y solo hace falta activarlo source [path name]/bin/activate
