Root Cause

Pip cannot parse the requirement string due to incorrect syntax (e.g., missing quotes, extra spaces).

generic

中文

由于语法错误（例如缺少引号、多余空格），pip无法解析依赖项字符串。

Workarounds

  1. 95% success Use proper requirement format with quotes 
    pip install 'numpy>=1.19.0,<2.0'
  2. 90% success Specify in requirements.txt correctly 
    echo 'numpy>=1.19.0,<2.0' >> requirements.txt
pip install -r requirements.txt

Dead Ends

Common approaches that don't work:

  1. Removing version specifiers entirely 70% fail

    Loses version constraints; may install incompatible version.

  2. Using semicolon instead of comma 90% fail

    Pip uses commas for multiple constraints; semicolon is invalid.
