Public bug reported:

Hi,

When trying to install a fresh DevStack, I got issues with pip 6.1. First issue:
https://bugs.launchpad.net/tempest/+bug/1440984

I worked around the first issue, but then I got this issue:

2015-04-07 10:08:34.241 | pkg_resources.DistributionNotFound: The 'argparse' distribution was not found and is required by oslo.config, python-keystoneclient, pysaml2

The problem is that newly released pip 6.1 doesn't want to install
argparse because argparse is part of the Python standard library:

fedora@myhost$ pip install argparse
Skipping requirement: argparse because argparse is a stdlib package
You must give at least one requirement to install (see "pip help install")

Workaround: downgrade pip to 6.0.8 and install argparse using pip (pip
install argparse).

A better fix is maybe to make argparse optional in keystone
requirements? It's now possible to add environment markers to
dependencies. Example:

futures; python_version < '2.7'
