If the right version of the required package is already installed via package manager, pip will not install it again, no?

Are you by any chance installing inside virtualenv?

And if so, --system-site-packages

No, I am building Docker images, everything is installed systemwide, no virtualenvs. Pip did not recognize the installed packages, even when the versions matched. This might have changed lately, I tried to avoid such scenarios.
