plugins resolved by pip instead of core pytest packages

[asmodehn]

Firstly I am not sure if this is problem of :

• pytest & plugins design
• pip-8.1.2
• how I use setuptools

But it s quite tricky to figure out what is going wrong, so I though I d post it here first.

Here is the issue :

error: The 'pytest' distribution was not found and is required by pyzmp

The full log is available at : https://travis-ci.org/asmodehn/pyros/jobs/139666793

This is probably reproducible by running :

python setup.py build --build-base ./build install --install-layout=deb --prefix=./build/install --install-scripts=./build/install/bin

with this package pyros-dev/pyros@2baf3fd, that uses this package https://github.com/asmodehn/pyzmp/releases/tag/0.0.10 that itself has pytest and pytest-timeout as a dependency.

Workaround
It seems I need to always list pytest after all pytest plugin packages in the dependency list. This triggers the pytest installation first...

[asmodehn]

Note this uses a virtualenv and works : https://travis-ci.org/asmodehn/pyros/jobs/139666794
It seems the problem appears only when we are using system + PYTHONPATH setup instead of virtualenv...

This confirms the workaround works : https://travis-ci.org/asmodehn/pyros/builds/139680687

This is a setuptools usage misstake

@asmodehn any updates on this, it still looks to me unrelated to pytest and i'd like to close the issue

[asmodehn]

I dont have anything more to report.

I fixed it for me, so feel free to close this, it s probably not a pytest
issue anyway.

But I find it strange that the order of dependencies in setup.py would
matter...

Sadly, I also dont have enough time and setuptools experience to
investigate that issue.
