openCV配置不完整，发生错误

Question

我正在尝试安装新的Python OpenCV我得到了以下错误，需要知道它的含义（以及可能如何解决）？

我安装得像这样（Mac在virtualenv中运行python 2.7）。

sudo port selfupdate
sudo port install opencv
sudo port -v install opencv +python27

然后：

sudo pip install pyopencv

...我收到了这个错误：

Error:

-- Configuring incomplete, errors occurred!

Configuring PyOpenCV via CMake...

Error: error occurred while running CMake to configure PyOpenCV.

You may want to manually configure PyOpenCV by running cmake's tools:

    mkdir build

    cd build

    cmake-gui ..    OR    cmake ..

    cd ..
