在MacOS Sierra上安装opencv-3.1.0以与python一起使用

Question

我最近升级到MacOS Sierra，我一直在处理许多问题(我提到它是因为它可能相关)。我试图安装opencv-3.1.0与python 2.7一起使用。这是不可能的。我从这里下载了opencv-3.1.0，解压缩并运行:

python platforms/osx/build_framework.py osx

从opencv-3.1.0目录。不想打印所有的输出，所以这里只有Error消息。

** BUILD FAILED **

The following build commands failed:

非常感谢你的帮助。谢谢。

Answer 1

看了这篇文章之后，我可以通过运行:
安装它了。brew install opencv3 --HEAD --with-contrib

这个问题似乎与QuickTime编解码器有关。您需要指定该库与ffmpeg一起安装，它应该可以工作。

brew install opencv3 --with-ffmpeg --with-tbb --with-contrib

Answer 2

尝试:

conda create -n opencv python=2

source activate opencv

conda install -c conda-forge openv ==3.1.0
