I'm having an issue with third-party dependencies published on my internal package repository. I can see that there is both a

.whl

and

.tar.gz

distribution available, and it installs fine with Poetry. However, when using resolves in pants and

pants generate-lockfiles

I receive an error similar to

No matching distribution found for your-package<0.3.0,>=0.2.2

. If I remove this dependency it occurs with the next internal package as well. I have set up the alternative repository in the

pants.toml

file and set up HTTP proxies as necessary. Before enabling resolves I was able to use

pants test

and run those fine, installing the same dependencies from the alternative repository.

Most probably pants isn't able to authenticate itself against your private repo. Have you tried what's suggested here https://www.pantsbuild.org/docs/python-third-party-dependencies from

Custom repositories

onward?

Hmm, I don't think that's the issue. The repository itself requires no additional authentication.
