python - 在 Windows10 上安装 pyglpk 包

问题描述

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 pyglpk 安装pip install glpk，这会给出以下错误消息：

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？

解决方案

我找到了一个解决方案，可以在不使用 PIP 的情况下在 python 中运行 glpk。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，您可以运行您的 pyomo 模型并选择 GLPK 作为您的求解器。
