根因分析

TOML 将 `version = 1.0` 解析为浮点数，但 PEP 621 要求 version 字段为字符串。

English

TOML parses `version = 1.0` as a float, but PEP 621 requires the version field to be a string.

解决方案

  1. 97% 成功率 
    Quote the version in pyproject.toml: `version = "1.0"` (or use dynamic version via setuptools_scm).
  2. 94% 成功率 
    Validate before building: `python -c "import tomllib,pathlib; print(tomllib.loads(pathlib.Path('pyproject.toml').read_text())['project']['version'])"`.

无效尝试

常见但无效的做法:

  1. 90% 失败

    The pyproject.toml validation happens before build isolation settings matter.

  2. 85% 失败

    Newer setuptools enforces the same PEP 621 type rules; the error persists.
