Make pytest-runner a conditional requirement in setup.py #16

Closed schamp closed 6 years ago

schamp commented 6 years ago

Description

I was installing dparse using pipenv, and during the setup.py egg_info process, it failed with an error similar to this: https://stackoverflow.com/questions/44375119/buildroot-installing-of-the-pytest-runner-package-fails

Upon digging in, I found the recommendation in the pytest-runner page (https://github.com/pytest-dev/pytest-runner#conditional-requirement) to make pytest-runner a conditional requirement only when tests are being invoked.

What I Did

I applied the patch as recommended, pointed my Pipfile.lock to the alternate repo, and the install worked properly.

Here's the error output from the pipenv install, if it's any use:
