1、安装cmake (是一个跨平台的安装工具)
brew install cmake
2、安装boost、boost-python（C++的程序库）
brew install boost brew install boost-python --with-python2.7
3、编译dlib
git clone https://github.com/davisking/dlib.git cd dlib mkdir build cd build cmake .. //以默认方式（SSE41指令）编译dlib cmake --build . cd .. sudo python setup.py install
4. 安装人脸识别的python库
pip install face_recognition
5、安装opencv-python
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-python
此时报错：
Cannot uninstall ‘numpy‘. It is a distutils installed project and thus we cannot accurate
解决方案：强行升级
pip install numpy --ignore-installed numpy
