【中文标题】无法导入 pynput.mouse 控制器、按钮

【英文标题】：Can't import pynput.mouse Controller, Button

【发布时间】：2021-12-29 14:24:03

【问题描述】：

我已经在终端中使用这两个命令安装了 pynput。

pip install pynput

python -m pip install pynput

两者都能正常工作，而且似乎软件包已正确安装 - 在终端中检查。

但是当我跑步时：

from pynput.mouse import Controller, Button

我不断收到此错误：

我正在运行最新的 python 版本 3.8 和 pip 20.1.1 可能是什么问题？

【问题讨论】：

您是否尝试重新安装？

是的，没用

【参考方案1】：

https://github.com/moses-palmer/pynput/issues/420 最新的 Pyobjc 打破了 pynput。将其降级到 7.3 可解决此问题。

学分：Error while importing pynput - dlsym(0x7f90f7d0c310, PyObjCObject_New): symbol not found

【讨论】：

我已经安装了 pyobjc 并将其降级到 7.3 - 仍然无法正常工作，我得到了同样的错误。
