In order to use pip and PyPI on your machine, you'll need to configure a pip.conf not a create repo file. See https://help.sonatype.com/display/NXRM3/PyPI+Repositories#PyPIRepositories-ConfiguringPyPIClientTools specifically "Download, search and install packages using pip" subsection.

PyPI has its own metadata and does not use the one detailed so the errors returning (404) are 'correct'.
