Root Cause

The function was called without the required string argument, likely due to incorrect API usage.

generic

中文

函数调用时缺少必需的字符串参数，可能是由于 API 使用错误。

Workarounds

  1. 95% success 
    from packaging.requirements import Requirement; req = Requirement('requests>=2.0')
  2. 85% success 
    help(Requirement)  # shows correct usage

Dead Ends

Common approaches that don't work:

  1. 90% fail

    An empty string is not a valid requirement; it will raise a different error.

  2. 100% fail

    Missing argument error persists regardless of passing style.
