根因分析

requirements.txt 中的版本说明符包含格式错误的版本号（例如双点、尾部操作符或说明符内部有空格），因此 pip 的 packaging 解析器在解析之前就拒绝了整行。

English

A version specifier in requirements.txt contains a malformed version number (e.g. double dots, trailing operators, or spaces inside the specifier), so pip's packaging parser rejects the whole line before resolving.

解决方案

  1. 98% 成功率 
    Edit requirements.txt:
  requests>=2.0
Then re-run:
  pip install -r requirements.txt
  2. 95% 成功率 
    python - <<'PY'
from packaging.requirements import Requirement
for i, line in enumerate(open('requirements.txt'), 1):
    line = line.strip()
    if not line or line.startswith('#'):
        continue
    try:
        Requirement(line)
    except Exception as e:
        print(f'line {i}: {line!r} -> {e}')

无效尝试

常见但无效的做法:

  1. 90% 失败

    pip delegates version parsing to packaging.version; the grammar is strict and unchanged across pip versions, so upgrading does nothing.

  2. 85% 失败

    Quotes become part of the requirement string and are still parsed as an invalid version, producing the same error.
