python-2.7 - Dlib安装python 2.7

Question

前海军陆战队员在这里! python和编码的新手。尝试为 python 2.7 安装 DLIB。我运行命令 pip install dlib 并不断收到此错误消息:

  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.

  ----------------------------------------   Failed building wheel for dlib

Along with this:
 Command "c:\python27\python.exe -u -c "import setuptools, tokenize;__file__='c:\\users\\pickfl~1\\appdata\\local\\temp\\pip-build-4qhao2\\dlib\\setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install

--single-version-externally-managed --compile" failed with error code 1 in c:\users\pickfl~1\appdata\local\temp\pip-build-4qhao2\dlib\

任何反馈或帮助都会很棒!以前的 jar 头所以请耐心等待，谢谢。
