@david-caro can you keep the .gitignore fixes in separate commit (or even better PR)?

[jirikuncar]

IMHO it's more complicated in real life. This case should never happen since it's obvious to fix. There might be however following case:

requirements = [
    'invenio-db[versioning]>=1',
]

extras_require = {
     'mysql': [
          'invenio-db[mysql]>=1',
     ],
}

$ requirements-builder -e mysql ...
invenio-db[versioning,mysql]>=1

[david-caro]

Yes, but now you see and are able to reproduce the issue, and most probably, the root of it is the same as the real-life example (still investigating).

@david-caro When you re-push, please also add yourself to the AUTHORS.rst file, thanks!

@david-caro IMHO we don't have to solve this limitation here since pip-compile already solves it for us.

pip compile needs a requirements.txt file as input, the step from setup.py->requirements.txt is done by requirements-builder and that step is the one that's failing:

This does not make sense here anymore, as the issue is down the stack trace, on pip pypa/pip#3878
