我试图构建dcn，但我得到了这些错误：

这是setup.py运行它的命令脚本：

我认为原因可能是我的Visual Studio版本是VS 2015，但我也安装了VS 2019，但我不知道如何强制pythonsetuptools使用VS2019，它默认使用VS2015。
谢谢。
因为我认为问题出在我的编译器版本上，我通过以下方式解决了：
首先我在命令提示符下运行以下命令：
SET MSSdk=1
SET DISTUTILS_USE_SDK=1
call "C:/Program Files (x86)/Microsoft Visual Studio/2019/Enterprise/VC/Auxiliary/Build/vcvarsall.bat" amd64 8.1 -vcvars_ver=14.23
然后我成功地构建了它。
