根因分析

需求行的版本说明符格式错误，通常是使用了单个 `=` 而非 `==`，或运算符之间有空格。

English

The requirement line has a malformed version specifier, often a single `=` instead of `==`, or a space between operators.

解决方案

  1. 98% 成功率 
    Change `requests >=2.0 <3.0` to `requests>=2.0,<3.0`
  2. 90% 成功率 
    python -c "from packaging.requirements import Requirement; [Requirement(l.strip()) for l in open('requirements.txt') if l.strip() and not l.startswith('#')]"

无效尝试

常见但无效的做法:

  1. 90% 失败

    requirements.txt is parsed by pip, not the shell; quoting does not change the grammar.

  2. 85% 失败

    The parser is strict by design; upgrading does not accept invalid syntax.

  3. 95% 失败

    The error occurs during parsing, before resolution.
