您收到的錯誤訊息表明暫停嘗試從 Python 套件索引 (PyPI) 下載套件時。此問題可能是由於網路連線緩慢或不穩定或臨時伺服器問題造成的。以下是解決該問題的一些建議：
檢查您的網路連接：確保您有穩定的網路連接，然後嘗試再次執行安裝命令。
升級 pip：透過執行以下命令確保您擁有最新版本的 pip：
python -m pip install --升級 pip
使用不同的包索引鏡像：PyPI 在全球範圍內有多個鏡像。您可以透過在安裝命令中新增 --index-url 選項來嘗試使用不同的鏡像。例如：
pip 安裝要求 --index-url=https://pypi.org/simple/
我希望這些建議可以幫助您解決超時問題並成功安裝“請求”模組。如果您還有任何疑問，請隨時詢問。
