1、看错误日志，如果出现了：
error: Microsoft Visual C++ 14.0 is required
看这篇博文解决方案，下载对应的版本就好了（注意：要细看评论区的内容）
我选择了百度网盘下载 Microsoft Visual C++ 15.0。
网盘链接（用XX猴，懂得都懂）：

2.经历了痛苦的等待后（实际很开心）
直接下载安装完后，又出现了新的问题（我随便拿别人的，我的python版本是3.8）：

其实真正的问题是：
你在C:Program FilesSCIPOptSuite-6.0.2include这个文件夹找不到scip.h文件。
这是因为你缺了SCIP优化组件，然后我就去这个网址：
https://www.scipopt.org/download.php?fname=SCIPOptSuite-6.0.2-win64-VS15.exe
下载了对应的版本。
上述链接的安装教程：
https://www.cnblogs.com/dengfaheng/p/10041488.html
按步骤安装好后其实问题还没有真正解决。
还是出现了同样的错误，那是因为prompt不能知道你到底把SCIP优化组件放在哪个地方，你要写一个命令
set SCIPOPTDIR=“C:Program Files你的SCIP优化组件安装的位置”（我是默认的）
再输入pip install pyscipopt==对应版本，因为它默认安装最新的4.x，所以出错才正常啊，所以它还是会说你在C:Program FilesSCIPOptSuite-6.0.2include这个文件夹找不到scip.h文件。
注意！
SCIP优化组件的版本 | 对应要下载的pyscipopt的版本 | 8.04.x7.03.x
那好，由于我下的是6.02版本，那么对应的就要下2.x版本的pyscipopt。
最后就大功告成了。
走过的弯路 找了要去解决这个error: command 'C:Program Files (x86)Microsoft Visual Studio2017EnterpriseVCToolsMSVC14.15.26726binHostX86x64cl.exe’错误的博客，可是没什么卵用。（算是抱怨吧）奶奶的，有那么几篇博文误人子弟，胡说八道，有的说去下SCIP优化组件的tgz解压后放到我的lib文件夹，还有的是要我更新python安装程序的version，现在慢慢的一堆黄黄难看的warning。
