在 Mu Editor 中将 pyautogui 安装为第三方模块时，如何解决此错误？

我正在阅读《用 Python 自动化无聊内容》的最后一章 - 第 20 章从安装和导入 pyautogui 开始，但我一直无法完成此操作。我已经能够在 Mac 上安装该模块，但我无法将其作为第三方模块添加到 Mu 编辑器中。这是我尝试将其作为模块添加到 Mu 编辑器时收到的错误：

我已经能够使用以下命令在我的 Mac 上成功安装 pyautogui：pip3 install pyautogui

我正在使用 python3.9 我在 macOS Sequia 15.3.1 上

但是，当我尝试将其作为第三方包添加到 Mu 编辑器时，它会退出并出现上述错误。

我搜索了互联网以寻找答案，并尝试过：

1. 重启
2. 卸载并重新安装 pyautogui 和 pyobjc
3. 以管理员身份安装 pyautogui
4. 按照 URL 转到 https://setuptools.pypa.io/en/latest/pkg_resources.htmlm（但说实话我不明白这个页面）。

我希望安装能够顺利完成，以便我可以将其导入 REPL 并使用 pyautogui 进行练习。

我特别困惑为什么它说 PyObjC：至少需要 Python 3.9，即使我正在运行 Python 3.9.6。

请帮忙！
