That's weird, it is and has always been a conditional dependency:

https://github.com/couchbase/couchbase-python-client/blob/2.5.9/setup.py#L194

https://github.com/couchbase/couchbase-python-client/commit/bbdd7d4e63da06c5447ec77e960536299ec44f5c

Will read through the 'poetry' issue here in detail soon.

For my own and others' reference, the maintainer mentions it here: https://github.com/sdispater/poetry/issues/1122#issuecomment-551755349

Not sure why the dependency isn't listed conditionally in the JSON file that PyPi produces.

https://github.com/python-poetry/poetry/issues/1122 is probably the issue mentioned above.

Also, from requirements.txt:

# Backward compatibility

enum34; python_version < '3.5'

That line has been there since 2017

All the requirements.txt are popped in the call to setup(), for both the setup_requires and install_requires keys. So all I can see that could be an issue is each of these have a newline at the end, and there are comments as well (though, they are supposed to be handled without problems by pip). We can easily strip them out, and see. But I see the correct stuff coming back from pip (commented in that ticket on poetry).

This appears to be a problem with PyPi not recognising our interpretation of PEP508 with respect to single/double quotes. The change we made to 2.5.9 appears to have at least meant that PyPI recognises it correctly. Have asked whether this has fixed the issue for users here:

wraptile - has this resolved the issue for you?

Thanks,

I think it's probably safe to assume this is fixed given this comment:

https://github.com/python-poetry/poetry/issues/1122#issuecomment-579187474

The version specifier was only just added in the latest release (December): https://pypi.org/pypi/couchbase/2.5.9/json

Our version marker is correct but not interpreted correctly by PyPi. However in 2.5.9 of PYCBC this is changed to work for all implementations of version markers.
