#838 Be able to use user's pip.conf in pip resolution Issue created by fhoering We have our own internal PyPi server and therefore need to do pip resolution with this server. Before what we were doing is to inject a custom

--index-url

into bdist_pex

python setup.py bdist_pex .. --index-url=<http://criteo/repository/pypi/simple>

and also via a custom fetcher when using pex via the Python API. Using custom configs is currently forbidden because vendored pip runs in isolated mode It would be nice be able to use pip.conf now as it would remove the need to add the custom server into the code (we already have

pip.conf

file set up on all our platforms) Could we introduce an additional flag here? Something like "--no-pip-isolated" for example. pantsbuild/pex
