this is what I have used for the past few years. I put my unversioned requirements in a subdir and run this when I want to bump versions.

#!/bin/bash -x WHEELHOUSE="/usr/local/wheelhouse" [ -d "$WHEELHOUSE" ] || ( sudo mkdir -p /usr/local/wheelhouse/ ; sudo chmod -R 0777 /usr/local/wheelhouse/ ) deactivate set -e cd .requirements for reqfile in requirements*txt ; do TEMPDIR="$(mktemp -d)" virtualenv -ppython3 "$TEMPDIR" . "$TEMPDIR"/bin/activate pip install -U pip pip install -U wheel pip wheel --find-links="$WHEELHOUSE" --wheel-dir="$WHEELHOUSE" -r $reqfile pip install --find-links="$WHEELHOUSE" -r $reqfile pip freeze | grep -v "pkg-resources" | sort > "../$reqfile" rm -rf "$TEMPDIR" done wait
