This is annoying for AWS lambdas too, because you have to bundle the dependencies and zip it. It's pretty trivial to go Pipfile -> requirements.txt -> pip install -t if you use a Makefile, but it's definitely an omission. I asked about it on their github though and it is a known issue, hopefully it'll be there soon.
