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

+Then you can install via:
+~~~bash
+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.
+## pipx
+~~~bash
+python3 -m pip install --user pipx
+python3 -m pipx ensurepath
