Let's say I have two locations /A and /B in which I installed python packages using pip's "user sheme" PYTHONUSERBASE=/some/folder pip install --user SomePackage. When installing Files in /B, is there a way to make pip aware of the packages installed in /A and avoid a double installation of packages?
Background: Our software stack is modularized using environment-modules. Modules are composable in the sense that each module should be its own, immutable entity but can depend on other modules.
- We have a python-base package which installs e.g.
pandasandnumpyusingPYTHONUSERBASE. - A python-bindings package depending on python-base and my-cpp-app should be introduced
I would like pip to pick up the packages in python-base and not reinstall them in python-bindings for two reasons
- Save space (not important)
- Ensure that versions of requirements are consistent and therefore compatible between each other (very important)
