Question

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

我做错什么了？在

我在64位Windows10机器上运行Python2.7。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。在

它仍然不能让我发布问题，所以这里有更多的文本，也许现在它可以工作了。还是不行。也许现在？在

Answer 1

Installation instructions表示：

SCIPOPTDIR needs to have a subdirectory lib that contains the library.

Additionally, if you're building PySCIPOpt from source, i.e. not using the precompiled egg or wheel, you also need to place all SCIP header files into a directory include next to lib (this is done automatically by make install INSTALLDIR=$SCIPOPTDIR SHARED=true of the SCIP Optimization Suite)

所以首先需要安装SCIP优化套件。在

Answer 2

这个问题已经在这里回答：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"

或者类似的东西。在
