我对 Jupiter 的使用不熟悉，并且已经设置了一个内核，但是一个错误阻止了任何事情的发生。任何帮助，将不胜感激。下面的文字是我点击内核错误时出现的错误。

【问题讨论】：

这能回答你的问题吗？ ImportError: no module named win32api

标签： kernel jupyter

【解决方案1】：

我遇到了类似的问题。我尝试使用 pip 重新安装 pywin32 软件包，但它也不起作用

pip install pywin32

解决我的问题的方法是使用conda 安装它

conda install pywin32

包的版本是一样的（227），但是 conda 做了一些 pip 不做的事情。
