我在Windows 10计算机上尝试为Jupyter Notebook设置pypy3内核时遇到问题。
按照其他两个相关线程（1，2的指示，我已经将ipykernel与命令pypy3 -m pip install ipykernel一起使用，但似乎安装有时会出错：

是否有可能解决该pywin32错误？
任何帮助将不胜感激。
尝试一下：
下载适当的python版本+ Os特定的库，并将其解压缩到安装上述所有模块的文件夹中。
https://pypi.org/project/pywin32/#files
[如果我们要为python安装此文件，则我们将提取的文件手动放入
C：\ Users \ admin \ Python \ Python37 \ Lib \ site-packages（默认python安装路径）
其中从pip下载是个问题。
