`resampy` test failures

[hunterhogan]

At this fork/branch, I am attempting to create typeshed stubs for resampy, but I have some test failures that I don't know how to resolve.

Py 3.14

pre-commit Failed
  Check the output of pre-commit for more details.
  This could mean that there's a lint failure on your code,
  but could also just mean that one of the pre-commit tools
  applied some autofixes. If the latter, you may want to check
  that the autofixes did sensible things.

I'm assuming the other failures are due to the unknown type information from numba and numpy.

Py 3.9

Since the errors are displayed after the line Running mypy for Python 3.9..., I tried running the tests directly in Python 3.9.

The script cannot install black, but I doubt that is a real problem.

But the test still says it can't find numba or numpy even though they are installed in the Python 3.9 environment.

What next?

How do I cure these defects so I can make a pull request?

[donbarbos]

Hello! As far as I can see, the issue seems to be related to the fact that these dependencies are not listed in requires in the METADATA.toml file (see CONTRIBUTING.md)
I’d also suggest opening a PR in cases like this, that way the problem will be easier to spot by running checks correctly and better understanding what's actually going on.

[hunterhogan]

@donbarbos Thank you. This is my first time trying to add a new package, and I guess I misunderstood that part.
