我在Windows 10中使用vs代码。当我使用pip在vs代码中安装face_recognition时，出现以下错误，我也尝试在安装face_recognition之前安装dlib。

You must use Visual Studio to build a python extension on windows. If you
are getting this error it means you have not installed Visual C++. Note
that there are many flavors of Visual Studio, like Visual Studio for C#
development. You need to install Visual Studio for C++.

根据face_recognition包的文档，为了在Windows上成功安装face_recognition，需要安装MS Visual Studio C ++编译器和CMake以及Boost。 （这是构建face_recognition所需的dlib依赖项）
在Github软件包中有完整的过程，其链接如下，其中包括：https://github.com/ageitgey/face_recognition/issues/175

答案很简单。您必须按照说的去做。转到VS安装程序，然后安装VS for C ++和C＃。原因是这些模块使用C代码，而在使用Visual Studio时，必须对其进行编译，以便可以编译C ++代码
