通过 pip 在 Python 2.7 (Windows 10) 上安装 PySCIPOpt 不起作用

Question

我刚刚尝试通过执行“pip install pyscipopt”来使用 pip 安装 PySCIPOpt，但是我收到以下错误消息：

我做错了什么？

我在 64 位 Windows 10 机器上运行 Python 2.7。它不允许我发布这样的问题，所以我从下面的错误消息中删除了一些明显的部分。

它仍然不允许我发布问题，所以这里还有一些文字，也许现在它会起作用。它仍然没有。也许现在？

Answer 1

这里已经回答了这个问题：https://github.com/SCIP-Interfaces/PySCIPOpt/issues/102

除了安装 SCIP Opt Suite 之外，缺少的是设置 SCIP Opt Suite 的安装路径：

set SCIPOPTDIR="C:\Program Files\SCIPOptSuite"

或类似的东西。

Answer 2

Installation instructions 说：

SCIPOPTDIR 需要有一个包含该库的子目录 lib。

此外，如果您从源代码构建 PySCIPOpt，即不使用预编译的 egg 或 wheel，您还需要将所有 SCIP 头文件放入 lib 旁边的目录中（这由 make install INSTALLDIR=$ 自动完成SCIP 优化套件的 SCIPOPTDIR SHARED=true)

所以首先你需要安装 SCIP 优化套件。
