Root Cause

The requirements line contains an unquoted space or stray text, so pip cannot parse it as a requirement and falls back to interpreting it as a local path.

generic

中文

requirements 行包含未加引号的空格或多余文本，pip 无法将其解析为需求，于是回退为将其解释为本地路径。

Workarounds

  1. 94% success 
    # requirements.txt: foo==1.0
python -c "from packaging.requirements import Requirement; [Requirement(l.strip()) for l in open('requirements.txt') if l.strip()]"
pip install -r requirements.txt
  2. 90% success 
    foo==1.0; python_version >= '3.9'

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Parsing behavior is stable; the malformed line still fails.

  2. 85% fail

    Adding a find-links path does not make the malformed requirement valid.
