Python：安装face_recognition时CMake错误

Question

我正在尝试安装face_recognition，并且已经安装了dlib，CMake，numpy，scipy和Boost。 但是当我跑步时

pip install face_recognition

我收到此错误：

Invoking CMake setup: 'cmake c:\Users\Julian\Desktop\deepfakes-master\dlib-master\tools\python -DCMAKE_LIBRARY_OUTPUT_DIRECTORY=c:\Users\Julian\Desktop\deepfakes-master\dlib-master\build\lib.win32-3.6 -DPYTHON_EXECUTABLE=C:\Users\Julian\AppData\Local\Programs\Python\Python36-32\python.exe -DUSE_AVX_INSTRUCTIONS=yes -DCMAKE_LIBRARY_OUTPUT_DIRECTORY_RELEASE=c:\Users\Julian\Desktop\deepfakes-master\dlib-master\build\lib.win32-3.6'
-- Building for: NMake Makefiles
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error in CMakeLists.txt:
  The CMAKE_C_COMPILER:

cl

  is not a full path and was not found in the PATH.

  To use the NMake generator with Visual C++, cmake must be run from a shell
  that can use the compiler cl from the command line.  This environment is
  unable to invoke the cl compiler.  To fix this problem, run cmake from the
  Visual Studio Command Prompt (vcvarsall.bat).

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

我不太了解这意味着什么。 任何帮助，将不胜感激

Answer 1

您需要下载 python版本的dlib的.whl包， 注意最低为19.7

为您的Windows 版本下载最新版本的cmake 。
在安装cmake时，请确保您勾选了将其添加到系统路径的选项。

最后pip install face_recognition
