Things have gotten better since I moved everything to a single

python_requirements

target. The one thing that seems to linger though is that certain transitive 3rd party deps aren't picked up. As of now it seems like the

mock

dependency isn't pulling in a transitive dependency on

setuptools

, so tests that use

mock

fail like:

import mock.mock as _mock
/Users/navneeth.jayendran/.cache/pants/named_caches/pex_root/venvs/s/1dd3906e/venv/lib/python3.7/site-packages/mock/mock.py:69: in <module>
    from pbr.version import VersionInfo
/Users/navneeth.jayendran/.cache/pants/named_caches/pex_root/venvs/s/1dd3906e/venv/lib/python3.7/site-packages/pbr/version.py:25: in <module>
    import pkg_resources
E   ModuleNotFoundError: No module named 'pkg_resources'

Manually including

setuptools

in the

dependencies

field of those tests fixes it, although it's not so nice. Also note I'm including

setuptools

in a different

python_requirement

from the main

python_requirements

I'm using, although these two don't overlap at all so there's never no ambiguity problems.
