Root Cause

A requirement string contains two version specifiers without a comma (e.g. `>=1.0<2.0`), which the PEP 508 parser rejects.

generic

中文

某个依赖字符串包含两个未用逗号分隔的版本说明符（如 `>=1.0<2.0`），PEP 508 解析器会拒绝。

Workarounds

  1. 98% success 
    Insert a comma between specifiers: `foo>=1.0,<2.0` in install_requires / pyproject.toml.
  2. 90% success 
    Validate requirements with `python -c "from packaging.requirements import Requirement; Requirement('foo>=1.0,<2.0')"` before packaging.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    They are not shell metacharacters inside a Python string; escaping does nothing.

  2. 80% fail

    The string is genuinely malformed regardless of parser version.
