Root Cause

An extras_require entry uses a specifier set the installed packaging/setuptools cannot parse, often due to stray whitespace, a trailing comma, or a duplicate/conflicting operator.

中文

extras_require 条目使用了已安装的 packaging/setuptools 无法解析的说明符集合，常由于多余空格、尾随逗号或重复/冲突的运算符。

Workarounds

  1. 95% success 
    Simplify the specifier to a valid PEP 440 set, e.g. `'>=1.0,<2.0,!=1.5'` (no spaces, no trailing comma).
  2. 90% success 
    Validate with `python -c "from packaging.specifiers import SpecifierSet; SpecifierSet('>=1.0,<2.0')"`.

Dead Ends

Common approaches that don't work:

  1. 85% fail

    Whitespace is not the issue; the specifier set itself is malformed.

  2. 75% fail

    Shifts the same parse error to a different field.
