stankevich/python Module to upgrade pip

edit

The default version of pip is 1.1.I want to upgrade the version of pip to 8.1.1.I don't see any option to do that in the module.I tried to `

           include python  
            python::pip { 'pip':
            path => ['/usr/bin'],
            ensure => '8.1.1',
            install_args => 'index-url=https://pypi.python.org/simple/',
            }

` But I get the following error :

Pip command not found

if I try to install any package

 python::pip { 'kafka-python':
 }
