Root Cause

A setup.cfg section or key is misspelled or unsupported by the installed setuptools version (e.g. a key from a newer setuptools used with an older one), so setuptools treats it as an invalid command.

generic

中文

setup.cfg 的某个节或键拼写错误，或不被已安装的 setuptools 版本支持（如用旧版 setuptools 使用新版才有的键），因此 setuptools 将其视为无效命令。

Workarounds

  1. 85% success 
    Upgrade setuptools to one that supports the key: python -m pip install --upgrade setuptools  # then rebuild
  2. 78% success 
    Validate the config: python -c "import configparser; c=configparser.ConfigParser(); c.read('setup.cfg'); print(c.sections())"  # compare keys against setuptools docs

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Disabling isolation doesn't fix an unknown config key; the same invalid command error is raised by the local setuptools.

  2. 75% fail

    Removes all metadata and entry points, causing a different failure (missing name/version) instead of fixing the key.
