Hmm. Having some issues resolving the constraints file after adding a new dependency (

ring

) that I'm not really sure why it's happening from looking at the output. The constraints file comes from

poetry export

, and Poetry is able to install the dependency just fine. Logs in thread.

The warning indicates wirerope was found but failed to build. Can you re-run with

--pex-verbosity=9

(I think 3 may actually be enough) and see if that reveals more?

Ah, perfect. Thanks! Seems like wirerope has some custom code in their setup.py that crashes due to setuptools' version containing a hash in the end.

ValueError: invalid literal for int() with base 10: '0+3acb925dd708430aeaf197ea53ac8a752f7c1863'

This looks likely, although Pex vendors a newer setuptools than that: https://github.com/youknowone/wirerope/blob/81c533d6df479cae80f74b5c298c4236f98f0158/setup.py#L3

Forgot to include the trace as well.

Aha, yeah.

Found a relevant issue on their issue tracker: https://github.com/youknowone/wirerope/issues/8

Pex vendors setuptools 44.0.0 here: https://github.com/pantsbuild/pex/blob/51bf80f27d238962a9b9ad3d52c818efa6233146/pex/vendor/__init__.py#L174-L182 And that results in a version of 44.0.0+...: https://github.com/pantsbuild/pex/blob/51bf80f27d238962a9b9ad3d52c818efa6233146/pex/vendor/_vendored/setuptools/setuptools-44.0.0%2B3acb925dd708430aeaf197ea53ac8a752f7c1863.dist-info/METADATA#L3

No problem! It's not super critical, I can work around it until wirerope hopefully fixes the issue on their end. Thanks for the help though, very much appreciated! 🙂

Ok, I sent a thorough fix. Hopefully they accept, but the project also seems dormant: https://github.com/youknowone/wirerope/pull/17
