安装Scip优化

Question

我正在尝试为python安装Scip优化，我正在跟踪一个视频，但是在视频中它正在安装Scip优化7，我正在安装Scip优化8，然后我也需要安装提示符。

pip安装pyscipopt

但它给了我一个错误：

Microsoft Windows [versão 10.0.19043.1645]

使用缓存的PySCIPOpt-4.2.0.tar.gz (661 kB)准备元数据(setup.py) .已完成的要求已满足: c:\users\matsu\appdata\roaming\python\python39\site-packages中的车轮(来自pyscipopt) (0.37.1)用于收集包的建筑车轮:pysciopbuilding轮子用于pyscipopt (setup.py)。错误错误:子进程-退出-有错误

注意:此错误源于子进程，很可能与pip无关。错误:遗留安装失败

在安装软件包时遇到了错误。[医]╰─>枕骨

注:这是上述软件包的一个问题，而不是pip。提示:有关故障的输出，请参阅上文。

有谁可以帮我？

我被同样的问题困住了。

通过安装用于桌面C++开发的"Microsoft C++ Build Tools“解决了这个问题，这在我之前的尝试中没有选择过。
