在Windows10上安装pyglpk package

[英]Installing pyglpk package on Windows10

我对安装软件包等的技术细节知之甚少,所以这可能是一个愚蠢的问题。 我只是先下载了 GLPK 并将其添加到路径中,然后尝试通过pip install glpk ,它给出了以下错误消息:

我尝试在网上搜索不同的安装教程或问题,但大多数是针对Linux/MacOS的,而不是针对Windows的。 我能做些什么呢?

我找到了在 python 中运行 glpk 的解决方案,而不使用 PIP。 我遇到了同样的问题,无法用 PIP 解决。

首先是下载 GLPK 求解器: https://sourceforge.net/projects/winglpk/ GLPK 基于 C。 您必须检查名为 glpsol.exe 的文件在哪里,并将该目录添加到路径中。 看这张图片中标注的 txt

之后,您可以运行 pyomo model 和 select GLPK 作为求解器。

它正在C:\Users\User\Anaconda3\include文件夹中寻找glpk.h 您可以通过将 GLPK 安装中的glpk.h复制到该文件夹中来使安装成功。 您还需要将glpk.lib复制到C:\Users\User\Anaconda3\libs中。
