Root Cause

The requirement string has malformed version specifiers or invalid characters.

generic

中文

需求字符串包含格式错误的版本说明符或无效字符。

Workarounds

  1. 90% success Use correct PEP 440 specifiers 
    pip install 'package_name>=1.0,<2.0' (with proper spaces)
  2. 70% success Check for typos in package name 
    Ensure no spaces in name

Dead Ends

Common approaches that don't work:

  1. Removing version specifiers entirely 40% fail

    May install incompatible version.

  2. Using single equals sign 60% fail

    Incorrect syntax.
