Python Wheel Metadata を取得する¶

概要¶

Python whl が要求する requires を調べたくなり、Python の Wheel ファイルからメタデータを取得する方法を調べた。importlib_metadata パッケージを使うと、Wheel ファイルからメタデータを取得できる。

setup¶

python -m pip install importlib_metadata

メタデータからrequiresの取得¶

from importlib_metadata import requires

print(requires("ipython"))
