Description

A submit job failed to install xdist. Has anyone seen this before?

http://jenkins.impala.io:8080/job/gerrit-verify-dryrun/445/console

Googling the error led me to this question from today on SO, but I still couldn't make sense of it: http://stackoverflow.com/questions/43288756/pytest-xdist-lookuperror-setuptools-scm-was-unable-to-detect-version

Running the following command on my local dev machine in a fresh virtualenv results in the same error:

pip install --no-binary --no-index --no-cache-dir --find-links infra/python/deps/ -r infra/python/deps/requirements.txt
