Root Cause

Code (directly or via a dependency) imports pkg_resources, which setuptools has deprecated and scheduled for removal. Common in older packages using pkg_resources.get_distribution or resource_filename.

generic

中文

代码（直接或通过依赖）导入了 pkg_resources，setuptools 已弃用该 API 并计划移除。常见于使用 pkg_resources.get_distribution 或 resource_filename 的旧包。

Workarounds

  1. 92% success 
    from importlib.metadata import version, distribution
print(version('requests'))

from importlib.resources import files
# replaces pkg_resources.resource_filename
path = files('mypkg').joinpath('data.txt')
  2. 80% success 
    python -W error::DeprecationWarning -c 'import mypkg'  # traceback shows importer
pip install -U <offending-package>  # upgrade to a release using importlib

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Hides the symptom only; the import still executes and will hard-fail once pkg_resources is removed. Also masks the real migration need.

  2. 75% fail

    Pins you to an unsupported setuptools, breaks modern build backends, and merely defers the removal. Downstream packages may require newer setuptools.
