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

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，请执行此处概述的安装说明。 最重要的是，您需要先安装 SCIP 优化套件。 您可以在此处获取 Windows 安装程序。 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）

Answer 2

我在尝试安装 python conda 时遇到此错误：

pip install conda

显示的错误是：

Building wheel for pycosat (setup.py) ... error
...
pycosat.c:10:10: fatal error: Python.h: No such file or directory 10 |
#include <Python.h>`

解决方案是安装具有所需标头的 python3-dev。

sudo apt-get install python3-dev

解决方案在这里： https ://github.com/conda/pycosat/issues/34

它不能解决 OP 的特定问题，但我最终在这里寻找解决此错误的方法。

Answer 3

尝试这个
pip install <package> --no-cache-dir
