Package: python-pip Version: 9.0.1-2+deb9u1 When attempting to pip install using --find-links with a directory of wheel files, this version of pip exits immediately if the python package cannot be found in the online PyPi repository. The correct behavior is to query the online PyPi repository, in addition to traversing the directory passed into --find-links which is the typical behavior of pip https://pip.pypa.io/en/stable/reference/pip_wheel/#cmdoption-f. In the below example /usr/local/gridspace/gspypi contained the wheel file for gsserializerfields.

Additionally, older distributions which had the 9.0.1-2 version of python-pip appear to exhibit the correct behavior as well. I am using Debian 9.
