Root Cause

The project has both pyproject.toml [project] and setup.py with conflicting metadata. setuptools does not merge them; the TOML takes precedence but inconsistency triggers errors.

generic

中文

项目同时包含 pyproject.toml [project] 和 setup.py，且元数据冲突。setuptools 不会合并它们；TOML 优先，但不一致会触发错误。

Workarounds

  1. 95% success 
    from setuptools import setup; setup()  # metadata in pyproject.toml
  2. 90% success 
    [project]\ndynamic = ["version"]\n[tool.setuptools.dynamic]\nversion = {attr = "mypkg.__version__"}

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Build isolation does not resolve metadata conflicts.

  2. 50% fail

    If setup.py contains custom commands or dynamic fields, deleting it breaks the build.
