Requirements from custom pypi repository

I have some issue with the packaging (via deploy) of my app when I use a private pypi server (hosted on S3 of course!).

Locally everything work well if I set my "extra-index-url" in my virtualenv config file. But when I package my app with chalice I have a "no module named ..." error.

Is there a way to add the "extra-index-url" to the config of chalice?

Start by tracing Chalice's dependency packaging during deploy and how the virtualenv configuration supplies extra-index-url. Check how dependencies are resolved for a private PyPI server hosted on S3. Done means a deployed package includes modules obtained through the configured extra-index-url without the reported import error.
