Hi guys. We are currently evaluating Pants. We are having issues adding a .whl dependency that is a simple url to an s3 bucket. The url is listed in the requirements.txt, but pants throws an error saying it can't find the file location when trying to build. Is there a special way to do this?

Are you using a direct reference? https://peps.python.org/pep-0440/#direct-references Although Pex and Pip understand a simple URL to a wheel, Pants does not IIRC.

Hi. The organization that publishes the library only allows hosts their code in an s3 bucket, so we can only fetch it via url

You can, but you need to use the format above:

projectname @ url

not just

url

It's not an s3 style url. Just regular https link

Yeah, so if the project name is "super-secret" (The wheel name), then you need to be repetitive for Pants and say "super-secret @ https://.....super-secret-....whl"

ok. let me try it

If that works, the relevant docs are here: https://www.pantsbuild.org/docs/python-third-party-dependencies#version-control-and-local-requirements The normal https URL case is a bit obscured - the examples are for git and file urls.

@enough-analyst-54434 That worked! Thank you so much!

Excellent. You're welcome.

Btw this PR might be worth tracking. It makes support for local requirements more ergonomic in some cases for Pants 2.14+ https://github.com/pantsbuild/pants/pull/16584. And rewrites the docs for local requirements to better explain them

The thing that got in the way here is Pants is more restrictive than the underlying tool(s) when parsing requirements.
