【问题描述】：
我在尝试在我的 Windows 10 机器上为 Jupyter Notebook 设置 pypy3 内核时遇到问题。
按照这两个其他相关线程（1、2）的说明，我已将ipykernel 与命令pypy3 -m pip install ipykernel 一起使用，但似乎安装在某些时候遇到了错误：

是否有可能绕过 pywin32 错误？
任何帮助将不胜感激。
【问题讨论】：
-
我认为您需要打开 ipykernel 和/或 pywin32 的问题。由于 pywin32 不支持 PyPy，要么 ipykernel 需要解决方法，要么 pywin32 应该支持 PyPy。
-
@mattip 谢谢你的指点，我可能会同时打开一个问题。
-
pywin32 不是 ipykernel 直接需要的。它似乎曾经是 jupyter_client 的依赖项，但它有 been changed。能不能浏览一下这里的包列表，找到哪个还依赖于pywin32？
-
啊，我看确实是jupyter_client，需要向右滚动。我想知道为什么仍然需要它？
