研究方向

使用所示的 python-inspector 命令和 requirements.txt 重現失敗，然後檢查 python_inspector/resolution.py 中 find_matches 和 _iter_matches 附近的程式碼，並追蹤從 python_inspector/api.py 發出的呼叫。對於 sys_platform 要求，命令能夠完成，並且針對所示的 macOS 情況解析出 torch==2.8.0 且不引發 NoVersionsFound，即表示完成。

描述

Python inspector command fails to scan when some packages include system platform information:
