将 pypy3 设置为 Jupyter Notebook 的内核时出现问题

Question

我在尝试为 Windows 10 机器上的 Jupyter Notebook 设置 pypy3 内核时遇到问题。

按照这 2 个其他相关线程 ( 1 , 2 ) 的说明，我已经使用ipykernel了该命令，pypy3 -m pip install ipykernel但似乎安装在某些时候遇到了错误：

有可能解决这个pywin32错误吗？

任何帮助将不胜感激。

对于 Python，模块是使用 CPython 编译的；对于 PYPY，模块是使用 RPython 编译的。

如果没有合适的模块可用或存在导入错误，您可以按照 pypy 文档中所述进行尝试。

如果是Python，我们可以
从这里手动下载适当的模块并将它们安装在默认的site-packages文件夹中：
