OSError: [Errno 9] 在 python 中使用 pip 指令時出現錯誤的檔案描述符

Question

當我嘗試在 cmd 中使用 pip 升級 pip 或安裝新軟體包時，顯示以下錯誤。我已經卸載並重新安裝了python，但問題仍然存在。我目前的python版本是3.7.3，我在Windows 10平台上運行它。此錯誤訊息顯示：

OSError: [Errno 9] 錯誤的檔案描述符

如何解決這個問題？以及導致此錯誤的原因。

我想最近（最近3年左右）Windows更新了一些安全性設置，可能是為了對抗勒索軟體，所以我們編寫的程序，例如python程序，只能讀/寫C:\Users\xxxxx\Documents內的文件文件夾。

我曾經創建一個特殊的工作資料夾作為 C:\working 並完成所有編碼工作以獲取樂趣，現在由於此安全更新，該程式不再工作。將完全相同的程式移到 C:\Users\xxxxx\Documents 中，然後它就可以像往常一樣運作了。
