Root Cause

Comparing a packaging.version.Version object directly with a string without conversion.

generic

中文

直接将 packaging.version.Version 对象与字符串进行比较而未进行转换。

Workarounds

  1. 95% success 
    from packaging.version import Version; v1 = Version('1.0'); v2 = Version('2.0'); print(v1 < v2)
  2. 90% success 
    from packaging.version import parse; print(parse('1.0') > parse('2.0'))

Dead Ends

Common approaches that don't work:

  1. 80% fail

    String comparison of versions (e.g., '1.10' > '1.9') is lexicographic and incorrect.

  2. 50% fail

    Equality may work but other comparisons still fail.
