        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++.

  ERROR: Failed building wheel for dlib
Failed to build dlib
ERROR: Could not build wheels for dlib, which is required to install pyproject.toml-based projects

解决方案

因为我的环境是anaconda的虚拟环境所以执行以下的语句

conda install -c conda-forge dlib

然后，他就成功安装了，注意中间会出现一个选择，输入y回车即可
