Hello - I am dealing with a pesky third party dependency. Only a source distribution is provided.

setup.py

script imports

numpy

which is not not specified either using

setup_requires

or

PEP-518 build-system requires

. Is there any pants mechanism to patch this type of undeclared dependency? https://www.pantsbuild.org/docs/python-third-party-dependencies#requirements-with-undeclared-dependencies addresses a similar issue, but not for build-dependencies.

There is not. You currently need to pre-build the wheel variants you need and host them on a custom index or custom find-links and configure `[python-repos]`: https://www.pantsbuild.org/docs/reference-python-repos

Ok thanks. 👍
