它仍然不让我发布问题，因此这里还有一些文字，也许现在可以了.仍然没有.也许现在?

It still doesn't let me post the question, so here's some more text, maybe now it will work. It still doesn't. Maybe now?

This question is already answered here: 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:

What was missing - apart from installing the SCIP Opt Suite - was to set the path to where the SCIP Opt Suite was installed:

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

或类似的东西.
