python - 将 pypy3 设置为 Jupyter Notebook 的内核时出现问题

Question

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，我使用了 ipykernel使用命令 pypy3 -m pip install ipykernel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。

对于 Python，模块使用 CPython 编译，对于 PYPY，这些模块使用 RPython 编译。

如果没有合适的模块可用或存在导入错误，您可以按照此处 pypy 文档中的说明进行尝试。

https://doc.pypy.org/en/latest/faq.html#module-xyz-does-not-work-with-pypy-importerror

如果是python，我们可以手动下载合适的模块
并从这里将它们安装在默认的站点包文件夹中:
