Root Cause

Setuptools expects setup.py to exist alongside setup.cfg when using setup.cfg for configuration.

generic

中文

当使用setup.cfg进行配置时，setuptools期望setup.py与setup.cfg位于同一目录。

Workarounds

  1. 95% success Create a minimal setup.py in the same directory 
    touch setup.py
# Content:
from setuptools import setup
setup()
  2. 90% success Move setup.cfg to the same directory as setup.py 
    mv /path/to/setup.cfg .

Dead Ends

Common approaches that don't work:

  1. Removing setup.cfg 60% fail

    Loses all configuration; may break build.

  2. Creating empty setup.py in parent directory 80% fail

    Must be in same directory; parent not checked.
