Poetry: Invalid requirement (2captcha-python>=1.2.0) found in awsapilib-3.1.3 dependencies, skipping

[iainelder]

Poetry skips the 2captcha dependency when resolving awsapilib's dependencies. It says:

Invalid requirement (2captcha-python>=1.2.0) found in awsapilib-3.1.3 dependencies, skipping

The missing dependency causes the AccountManager class to fail with a ModuleNotFoundError.

I can work around it by adding 2captcha-python to my own project, but I'd rather not.

Here's a full repro in an empty directory.

$ poetry --version

$ poetry new .

$ poetry add awsapilib

See discussion on this topic in the Poetry forum. I've shared it there to get some insight from the Poetry experts.

Thanks! Interesting bug :)

It may be a bug in Poetry, but it's not a bug in awsapilib itself, so I'll close this here. To avoid the problem, I think either Poetry has to relax its parsing of PyPI project names, or the 2captcha-python project has to change its name. Poetry doesn't like project names that start with digits.

awsapilib is now compatible with Poetry.

In python-poetry/poetry-core#607 I fixed it to accept dependency names starting with a number.

Poetry 1.6.0 and Poetry Core 1.7.0 contain my fix.

$ poetry --version
Poetry (version 1.6.1)

$ poetry new .
Created package tmp.2023_08_26.585ougjl in .

$ poetry add awsapilib
