can lead to Double requirement Exception

will explain better later, but think it's related to archive links being considered "unnamed" requirements #804 (comment)

It doesn't seem to be the case anymore.

pip wheel celery -w /tmp/test/

pip install --use-wheel --no-index --upgrade --ignore-installed /tmp/test/*

works fine.
