当 Cmake 报告错误并且重新安装不起作用时，如何在 macOS 中安装 dlib

Question

尝试为 face_recognition 下载dlib ，已经下载了 openCV 但在此过程中遇到错误/

我努力了：

1. pip install dlib ， pip3 install dlib和
2. brew install dlib

我在 1 中遇到了同样的错误，在 2 中遇到了不同的错误，如下：

“Error: The following formula
[#, #]
cannot be installed as binary package and must be built from source.
Install the Command Line Tools:
xcode-select –install”

然后我尝试运行xcode-select –intall并且也失败了......

无论如何，为了您阅读方便，我将尝试先为您手动挑选错误突出显示，如下所示：

_"ERROR: Command errored out with exit status 1:”_


_“package init file ‘dlib/__init__.py’ not found (or not a regular file)”_


_“Invoking CMake setup:…..

_“The C compiler . “/usr/bin/cc” . is not able to compile a simple test program.”_


_“CMake will not be able to correctly generate this project.”_


_” — Configuring incomplete, errors occurred!”_

如何解决安装 Dlib 的错误？ .

python 3.6 到 3.7.0 支持 dlib 19.17，如果 dlib 版本高于则它会导致 numpy 错误
