【问题描述】：
我正在尝试将 dlib 导入文件以检测人脸。我按照 davisking 的 github repo 上的说明进行操作。
所以当我尝试运行python setup.py install --no USE_SSE4_INSTRUCTIONS时出现以下错误：

我尝试打开和关闭USE_SSE4_INSTRUCTIONS。我也试过打开和关闭DUSE_AVX_INSTRUCTIONS。
有人对我可以尝试什么有什么建议吗？

您似乎缺少 X.org 包含。
-
如果你正在使用python3，那么你需要在
brew uninstall boost-pythonbrew uninstall boostbrew install boost-python --with-python3 --without-python之前这样做。
