根因分析

需求字符串使用分号表示环境标记，但语法错误或 packaging 版本太旧。

English

The requirement string uses a semicolon for environment markers, but the syntax is incorrect or the packaging version is too old.

generic

解决方案

  1. 95% 成功率 Use proper syntax with environment markers 
    Write: 'numpy; python_version < "3.8"' (note space after semicolon and proper quoting).
  2. 90% 成功率 Upgrade packaging to support modern syntax 
    Run: pip install --upgrade packaging

无效尝试

常见但无效的做法:

  1. Removing the semicolon and marker entirely 70% 失败

    Loses conditional installation logic.

  2. Using double quotes inside the marker 80% 失败

    Syntax remains invalid; markers require proper quoting.
