我安装了2个版本的python,但是cmake使用的是旧版本.如何强制cmake使用新版本？

得到此错误:

sudo: unable to resolve host coderw@ll
-- Could NOT find PythonLibs (missing:  PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) 
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108

我已经安装了:

1. sudo apt-get install python-dev

2. 环境变量已设置如下:

   PYTHON_INCLUDE_DIRS=/usr/include/python2.7 
   PYTHON_LIBRARIES=/usr/lib/python2.7/config/libpython2.7.so
   

   Run Code Online (Sandbox Code Playgroud)

位置python.h:/usr/lib/include/python2.7/python.h

pythonlibs的位置:/usr/lib/python2.7/ 如何解决这个问题？

我试图在Macbook Pro 2013年末与小牛队一起安装opencv.我没有找到任何二进制文件,所以我正在尝试构建它.
我试过http://www.guidefreitas.com/installing-opencv-2-4-2-on-mac-osx-mountain-lion-with-python-support
和http://forums.udacity.com/questions/ 100021223/installed-opencv-on-os-x-mountain-lion
在调用时生成错误2
(CMake Error at cuda_compile_generated_matrix_operations.cu.o.cmake:208)

在这个网站上搜索时,我在小牛队找到了opencv for python(我也尝试了自制软件,但是也产生了错误2,但没有任何进一步的信息)

我google了很多,但找不到任何解决方案对我有用.有没有人在小牛队上安装opencv？

谢谢

使用brew提供以下输出:

    brew install homebrew/science/opencv
