Root Cause

setuptools validates the version string against PEP 440. '1.0.0-beta' uses a hyphen which is not allowed; PEP 440 uses 'b' for beta, e.g. '1.0.0b0'. Pre-release separators must be normalized.

中文

setuptools 根据 PEP 440 校验版本字符串。'1.0.0-beta' 使用了连字符，这是不允许的；PEP 440 使用 'b' 表示 beta，例如 '1.0.0b0'。预发布分隔符必须规范化。

Workarounds

  1. 98% success 
    version='1.0.0b0'  # instead of '1.0.0-beta'
  2. 90% success 
    pip install setuptools_scm && echo '[tool.setuptools_scm]' >> pyproject.toml
  3. 85% success 
    python -c "from packaging.version import Version; Version('1.0.0-beta')"

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Legacy setup.py still validates version via packaging.

  2. 95% fail

    The value is already a string; the problem is its content.
