python-3.x - Jupyter笔记本电脑: Terminals not available

Question

昨天我在启动Jupyter Notebook时遇到了问题(突然我收到通知，python无法正常工作，但是在一切正常之前……)。因此，我决定升级到最新的python版本。现在，我可以启动jupyter notebook，但是出现以下错误消息:

Terminals not available (error was No module named 'winpty.cywinpty')

我遵循了setps descriebd here:
但是仍然会收到此错误消息。有没有办法解决这个问题？还是有人建议？
编辑:这是当我从cmd运行jupyter笔记本时得到的:

我在使用Python 3.9时遇到了同样的问题，并通过使用pipwin安装wheel和pywinpty来解决了这个问题:pip install pipwinpip uninstall wheelpipwin install wheelpip uninstall pywinptypipwin install pywinpty重新启动Jupyter后，错误消失了。
