无法通过pip在Python2.7(Windows10)上安装PySCIPOpt

Question

我刚刚尝试通过执行"pip install pyscipopt“来使用pip安装PySCIPOpt，但是我得到了以下错误消息：

我做错了什么？

我在64位的Windows10机器上运行Python2.7。

现在也不是。也许是现在？

Answer 1

这个问题已经在这里得到了回答：https://github.com/SCIP-Interfaces/PySCIPOpt/issues/102

除了安装SCIP Opt Suite之外，还缺少设置安装SCIP Opt Suite的路径：

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

或者类似的东西。

Answer 2

Installation instructions说：

SCIPOPTDIR需要有一个包含库的子目录库。

此外，如果您正在从源代码构建PySCIPOpt，即不使用预编译蛋或轮子，您还需要将所有SCIP头文件放在lib旁边的包含目录中(这是由SCIP优化套件的make install INSTALLDIR=$SCIPOPTDIR SHARED=true自动完成的)

因此，首先您需要安装SCIP优化套件。
