Root Cause

A package version string does not conform to PEP 440. This often happens with custom-built or vendored packages whose version was set from a git describe or CI variable containing invalid characters.

中文

包版本字符串不符合 PEP 440。这通常发生在自定义构建或内置包上，其版本从包含无效字符的 git describe 或 CI 变量设置而来。

Workarounds

  1. 80% success 
    from packaging.version import Version, InvalidVersion

def normalize(v):
    try:
        return str(Version(v))
    except InvalidVersion:
        return v.replace('-rc.', 'rc').replace('+', '.post')

print(normalize('1.0.0-rc.1'))  # 1.0.0rc1
  2. 85% success 
    # in setup.py
from setuptools import setup
setup(name='mypkg', version='1.0.0rc1')  # not 1.0.0-rc.1

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Pre-release flag doesn't relax PEP 440 validation; the version string is still invalid.

  2. 85% fail

    Ignoring installed packages doesn't change version parsing.
