我正在尝试在macOS 10.11.6上使用Anaconda3 python 3.6安装OpenCV 3.2.0，但我找不到方法。
我的Anaconda3已安装python 3.5.2，但如果我使用"conda create -n envname python=3.x" 命令创建一个新的虚拟环境，那么我的python版本将被升级到3.x。
$ conda create -n myvenv python
then it downloads and installs python 3.6 on the new myvenv. A simple search
$ conda search opencv
opencv 2.4.8 np17py27_2 defaults
在使用OpenCV3时没有得到任何结果
$ conda search opencv3
NoPackagesFoundError: Package missing in current osx-64 channels:
- opencv3
安装menpo opencv3构建时会出现以下冲突：
$ conda install -c menpo opencv3
Fetching package metadata ...........
Solving package specifications: .
UnsatisfiableError: The following specifications were found to be in conflict:
- opencv3 -> python 2.7* -> openssl 1.0.1*
- python 3.6*
Use "conda info <package>" to see the dependencies for each package.
我尝试使用Homebrew安装，但将其与Anaconda3的Python3链接似乎很困难：
$ brew install eigen tbb

==> Caveats
Python modules have been installed and Homebrew's site-packages is not
in your Python sys.path, so you will not be able to import the modules
this formula installed. If you plan to develop with these modules,
please run:
mkdir -p /Users/<username>/.local/lib/python3.5/site-packages
echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/<username>/.local/lib/python3.5/site-packages/homebrew.pth
