Error: [Errno 71] Protocol error: pyvenv
pyvenv-3.4 --without-pip name_of_environment
worked
looks like pip was not installed.
thanks for the help.
I am using Centos7 with vagrant and virtualbox on windows10.
I am trying to create pyvenv virtual environment to develop python web apps with django. I have installed python 3.4. 
However, when I type 
pyvenv-3.4 name_of_environment,
it gives back an error Error: [Errno 71] Protocol error: 'lib' -> '/vagrant/django_apps/app1/name_of_environment/lib64'
What is wrong?
