Description

When install pyarrow via poetry and executing same, a ModuleNotFoundError error can result.

Pyarrow has a dependency on pytz, but this dependency is not declared (the only dependency I see declared is numpy, see https://github.com/apache/arrow/blob/47d55752172af99fce629f8fe6177df6b41af1d3/python/setup.py#L576)

It would be helpful if pyarrow could declare its dependencies in such a way that tools such as poetry could automatically ensure they were present.
