根因分析

pip 将依赖项字符串按 PEP 508 语法解析；像 --no-deps 这样的标志不能嵌入到依赖项说明符中，必须作为单独的 CLI 参数传递。

English

pip parses requirement strings as PEP 508 syntax; flags like --no-deps cannot be embedded inside a requirement specifier and must be passed as separate CLI arguments.

解决方案

  1. 99% 成功率 
    pip install --no-deps 'requests==2.31.0'
  2. 98% 成功率 
    echo 'requests==2.31.0' > req.txt
pip install --no-deps -r req.txt

无效尝试

常见但无效的做法:

  1. 85% 失败

    Quoting does not change parsing; pip still treats the quoted text as one requirement and rejects the option token.

  2. 90% 失败

    requirements.txt lines are requirement specifiers, not command lines; pip errors out on the same Invalid requirement message.

  3. 95% 失败

    Backslashes are not valid in PEP 508 requirement names and produce a different parse error.
