根因分析

版本字符串不符合 PEP 440。像 '!' 这样的字符或格式错误的前发布分隔符（'-beta' 而非 'b'）会被 packaging.version.Version 拒绝。

English

A version string does not conform to PEP 440. Characters like '!' or malformed pre-release separators ('-beta' vs 'b') are rejected by packaging.version.Version.

解决方案

  1. 85% 成功率 
    from packaging.version import Version, InvalidVersion
raw = '1.0.0-beta.1+build_42!'.rstrip('!')
v = Version(raw.replace('-beta', 'b'))
print(v)  # 1.0.0b1+build.42
  2. 90% 成功率 
    # pyproject.toml
[project]
version = "1.0.0b1"  # PEP 440 pre-release form
# or use dynamic versioning from git tags via setuptools-scm

无效尝试

常见但无效的做法:

  1. 90% 失败

    LegacyVersion was removed in packaging 22+; importing it raises ImportError. Even when available, comparisons are unreliable.

  2. 80% 失败

    Produces a different version (e.g. '100beta1build42') that no longer reflects intent and may collide with real releases.
