在Mavericks上安装OpenCV for Python

Question

我正在尝试在2013年底的Macbook Pro上安装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/installing-opencv-on-os-x-mountain-lion
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，我发现 opencv 在特立独行的 python 上（我也尝试了自制软件，它也产生了错误 2，但没有任何进一步的信息）

我

用谷歌搜索了很多，但没有找到的解决方案对我有用。有没有人在小牛队安装 opencv ？

谢谢

使用 brew 提供以下输出：

    brew install homebrew/science/opencv

通过使用对学生免费的顶篷（https://www.enthought.com/products/canopy/）为我解决了问题

Answer 1

您可以正常使用brew安装它。

brew install homebrew/science/opencv

或

brew tap homebrew/science
brew install opencv

这就是我在我的特立独行者身上安装它的方式，它工作得很好。

Answer 2

$ brew search opencv
        homebrew/science/opencv
$ brew install homebrew/science/opencv

安装后，有注意事项：

==> 注意事项如果您需要 Python 来查找已安装的站点包：

mkdir -p ~/Library/Python/2.7/lib/python/site-packages

echo '/usr/local/lib/python2.7/site-packages'> ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth

所以，只要做

  mkdir -p ~/Library/Python/2.7/lib/python/site-packages
  echo '/usr/local/lib/python2.7/site-packages' > ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth
