如何修复pythonnet安装过程中的错误

问题描述

当我尝试使用以下命令时：

pip install pythonnet

我看到您可以在下面看到的错误：

我该如何解决？我尝试使用 PyCharm 安装该软件包，但出现相同的错误。有什么想法吗？

解决方法

从 docs 我可以看到它不支持 python 3.9 所以你可以从 here

由于您的 python 版本是 3.9，因此请根据您的系统 32 位或 64 位 python 版本下载 pythonnet‑2.5.2‑cp39‑cp39‑win_amd64.whl

并提供安装为 pip install wheel-file

的完整路径

pip pip python python.net
