    WARNING: You are using pip version 19.1, however version 19.1.1 is available.
    You should consider upgrading via the 'python -m pip install --upgrade pip' command.

因为安装dlib前需要先安装cmake 和boost。然后才能正确安装dlib

pip install boost
    pip install cmake
    pip install dib

测试安装结果：

    Type "help", "copyright", "credits" or "license" for more information.
    >>> import dlib

大功告成！
