      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++.

解决办法

pip install face_recognition -i https://pypi.douban.com/simple

–no-dependencies 强制安装忽略依赖项，实在安装不上再试着加上

按需使用

pip install --no-dependencies face_recognition -i https://pypi.douban.com/simple

1.若还是无法解决，那就安装cmake

pip install cmake -i https://pypi.douban.com/simple

2.若还是无法解决，那就安装Visual Studio 2017

Visual Studio 2017
