Root Cause

The version string does not conform to PEP 440; local version labels must start with a digit after the '+'.

generic

中文

版本字符串不符合 PEP 440；本地版本标签在 '+' 后必须以数字开头。

Workarounds

  1. 95% success 
    version = '1.0.0rc1+build123'  # local label 'build123' starts with digit
  2. 0% success 
    from packaging.version import Version; v = Version('1.0.0rc1+build123')  # will raise error; fix the string first

Dead Ends

Common approaches that don't work:

  1. 50% fail

    Removing build metadata may lose important build information; parsing may still fail if other parts are invalid.

  2. 80% fail

    The version is still invalid per PEP 440; older libraries may not raise error but will parse incorrectly.
