You can achieve this with a constraints file. Just put all your constraints into that file:

constraints.txt

google-api-core==1.16.0

Then you can install via:

python -m pip install -c constraints.txt google-cloud-secret-manager

This will try every version of google-cloud-secret-manager, starting from the most recent version, until it finds a version that is compatible with the given constraints.

python3 -m pip install --user pipx
python3 -m pipx ensurepath
