ERROR: botocore 1.12.198 has requirement docutils<0.15,>=0.10, but you'll have docutils 0.15.1 which is incompatible.
Installing collected packages: sqlparse, pytz, django, jmespath, six, python-dateutil, urllib3, docutils, botocore, s3transfer, boto3, PyYAML, placebo, click, kappa, tqdm, wsgi-request-logger, Unidecode, python-slugify, durationpy, idna, certifi, chardet, requests, Werkzeug, cfn-flip, troposphere, toml, lambda-packages, argcomplete, hjson, future, zappa

Doesn't appear to break anything, but might be worth pinning to docutils 0.15 to avoid the error message, if that's possible.

This is on a recent version of Debian, Python 3.7.3, pip version 19.2.1

Start by reproducing pip install django zappa in a fresh virtualenv with Python 3.7.3 and pip 19.2.1, then inspect the dependency declarations involved in botocore and docutils. Done means the installation no longer reports the docutils version conflict, while the requested packages still install successfully.
