【问题描述】：

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”，但我收到错误“pyscipopt 构建轮子失败”。我不知道这是什么意思或如何解决这个问题，有人可以帮助我吗？

标签： python anaconda scip


【解决方案1】：

这是实际的错误：

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

要解决此问题，请按照here 的说明执行安装说明。最重要的是，您需要先安装 SCIP 优化套件。您可以获取 Windows 安装程序here。安装后，您需要设置一个环境变量，告诉 PySCIPOpt 安装程序在哪里可以找到用于链接的 SCIP 库：

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

（假设您使用 SCIPOptSuite 的默认安装路径）

【讨论】：

  • 谢谢！我已经安装了 SCIP 优化套件。我已阅读说明，但我不知道该怎么做，因为我不明白。我不知道在哪里输入“set SCIPOPTDIR=”以及我必须写什么路径。以及如何设置一个环境变量来告诉 PySCIPOpt 安装程序在哪里可以找到 SCIP 库进行链接？这可能是愚蠢的问题，但我真的不擅长这个，我只需要安装它来完成我的作业。
  • 我编辑了我的答案。您需要在同样用于运行pip install 的控制台/shell/命令行中定义环境变量。
  • 谢谢，我再次安装了 SCIPOptSuite 并设置了一个环境变量，告诉 PySCIPOpt 安装程序在哪里可以找到 SCIP 库进行链接，但我得到了同样的错误...
  • 您能否确认目录SCIPOPTDIR\include 和SCIPOPTDIR\lib 存在，并且其中有一个scip/scip.h 文件和另一个中的一些库？安装程序甚至会打印出使用了哪个目录 (Using SCIP library &lt;scip&gt; at ...)。请检查这是否正确。
【解决方案2】：

试试这个
pip install &lt;package&gt; --no-cache-dir

【讨论】：

  • pip3 install wheel 或尝试更新轮子
