在Windows10上安装pyglpk包
提问于 2019-11-09 17:18:36
我对安装软件包的技术细节没有太多的了解，所以这可能是一个愚蠢的问题。我只需先下载GLPK并将其添加到路径中，然后尝试通过pip install glpk安装pyglpk，这会给出以下错误消息：

我找到了一个在python中运行glpk而不使用PIP的解决方案。我得到了同样的问题，不能用PIP解决它。
第一件事是下载GLPK求解器：https://sourceforge.net/projects/winglpk/ GLPK是基于C的。您必须检查哪里有一个名为glpsol.exe的文件，并将该目录添加到路径中。look remarked txt in this image
之后，您可以运行pyomo模型并选择GLPK作为求解器。

它在文件夹C:\Users\User\Anaconda3\include中查找glpk.h。您可以通过将glpk.h从GLPK安装复制到该文件夹来使安装成功。您还需要将glpk.lib复制到C:\Users\User\Anaconda3\libs中。
