Python 平面散列映射。h：错误C3203:&x27；模板迭代器'；：非专用类模板

我已尝试构建，但出现以下错误：

我想原因可能是我的visual studio版本是VS 2015，但我也安装了VS 2019，但我不知道如何强制python

setuptools

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，我通过以下方法解决了：

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

然后我成功地建造了它

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
