Thanks @asottile!

ERROR: Error installing 'file:///home/travis/build/pytest-dev/pluggy': editable mode is not supported for pyproject.toml-style projects. pip is processing this project as pyproject.toml-style because it has a pyproject.toml file. Since the project has a setup.py and the pyproject.toml has no "build-backend" key for the "build_system" value, you may pass --no-use-pep517 to opt out of pyproject.toml-style processing. See PEP 517 for details on pyproject.toml-style projects.

I fixed the installation error by avoiding installation. I don't have the merge bit here, heh
