编辑：对于那些感兴趣的人，创建者当前正在研究此here。
我正在尝试使用pygalmesh安装pip install pygalmesh，具体取决于Eigen。我已经下载了Eigen，但是pip安装程序并不“知道”这一点。它返回以下错误消息：
ERROR: Could not build wheels for pygalmesh which use PEP 517 and cannot be installed directly
更具体地说：
fatal error C1083: Cannot open include file: 'Eigen/Dense':
Pygalmesh的github有一个我可以编辑的setup.py文件，但是我不知道如何安装pygalmesh。仍然使用pip吗？
是否可以编辑setup.py文件，以便安装程序知道Eigen / Dense的位置？因为我有一台Windows PC，所以我至少认为/需要更改为\。但是我找不到要编辑的setup.py。
我在web以及here的其他位置都找到了有关此问题的对话。我不知道如何实现这些帖子中所讨论的内容。我也曾尝试通过conda安装本征，例如here。这也没有用。
