I'm trying to install dependencies inside of tox, which I believe needs --system (to install into tox's virtualenv instead of into pipenvs own virtualenv). See also #154.

However, pipenv sync, which is the new way to install dependencies from Pipfile.lock does not support --system (it seems it was intentionally left out initially in #1463), so I have to resort to pipenv install.

It seems it would be useful to support --system for sync as well.

I really would appreciate having pipenv sync --system as well. This would be the preferred way to use pipenv in a Docker container. At the moment I'm using pipenv install --system --deploy which is not as great of a solution.

It seems that this issue has stalled. Would it make sense to take
aca8e12 and make a PR from it?
