如何在Google Colaboratory上导入并使用PyWhatKit？

Question

我想使用 pywhatkit 库自动从 Google Colab 在 WhatsApp 上发送消息。到目前为止，我已尝试执行以下操作：

pip install pywhatkit

输出：

我还尝试查看 pip list 是否安装了它，它说它已安装：

pip list

输出：

....
....
pywhatkit     5.3
....
....

当我尝试导入时，它显示错误。

import pywhatkit

输出：

---------------------------------------------------------------------------

--> 681             raise KeyError(key) from None
    682         return self.decodevalue(value)
    683 

KeyError: 'DISPLAY'

此问题的解决方法或解决方案是什么？
