python - 如何修复“pyscipopt 构建轮子失败”？

Question

我正在尝试为作业安装 Pyscipopt。学校网站上有一个安装指南，问题是它在我的笔记本电脑上不起作用。我必须在 Anaconda Prompt 中编写“pip install pyscipopt”，但出现错误“pyscipopt 构建轮子失败”。我不知道这意味着什么或如何解决这个问题，有人可以帮助我吗？

Answer 1

This is the actual error:

 Cannot open include file: 'scip/scip.h': No such file or directory

To resolve it, please carry out the installation instructions as outlined here. Most importantly, you need to install the SCIP Optimization Suite first. You can get the Windows installer here. After installing, you need to set an environment variable telling the PySCIPOpt installer where to find the SCIP library for linking:

 set SCIPOPTDIR="C:\Program Files\SCIPOptSuite-6.0.2"
 pip install pyscipopt

(assuming you used the default installation path for the SCIPOptSuite)
