【问题描述】：

无法在 macbook OS X Yosemite Ver 10.10.5 中安装“opencv”

尝试了默认安装，没有帮助然后我安装了Python的Anaconda发行版，之后再次尝试以下，我收到消息说opencv已安装，但我无法通过python控制台使用它。安装Anaconda后，我跟着this tutorial安装opencv

  $sudo chmod 777 /usr/local/include/
  $brew link eigen jpeg libpng libtiff ilmbase openexr numpy
  $sudo chmod 777 /usr/local/lib/pkgconfig
  $brew link eigen jpeg libpng libtiff ilmbase openexr numpy
  $brew install opencv --evn=std
  $brew link eigen jpeg libpng libtiff ilmbase openexr numpy
  $sudo chmod 777 /usr/local/lib/
  $brew link eigen jpeg libpng libtiff ilmbase openexr numpy
  $brew install opencv --evn=std
  $python
  $mkdir -p /Users/vikramchindam1/.local/lib/python2.7/site-packages
  $echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/vikramchindam1/.local/lib/python2.7/site-packages/homebrew.pth

然后启动python控制台

 $python

>>> import cv
Python 2.7.11 |Anaconda 2.5.0 (x86_64)| (default, Dec  6 2015, 18:57:58)

>>> import cv

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

ImportError: No module named cv

我在一段时间内多次安装了 Anaconda，这是一个问题吗？以下是我的 .bash_profile 中的条目

alias textedit='open -a TextEdit'

# added by Anaconda 2.2.0 installer
export PATH="/Users/vikramchindam1/anaconda/bin:$PATH"

export PATH="/Users/vikramchindam1/Installations/Anacon-Python2-7/anaconda/bin:$PATH"
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

最后一个条目“export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH”是我在通过这个命令“brew install opencv --env=std”安装opencv后添加的

请帮帮我，提前谢谢。

【问题讨论】：

尝试导入cv2
试过但没用 >>>import cv2 .. ImportError: No module named cv2
从 Anaconda 调用 cv2，而不是从你的 normal shell
在Anaconda下打开了一个终端，试过但同样的错误drive.google.com/file/d/0Bxed_8T6OPe4OWxCdndwdHR1bDQ/…

【解决方案1】：

您必须使用“conda”工具在 Anaconda 中安装 OpenCV。您可以尝试在终端中输入。

conda install -c https://conda.binstar.org/menpo opencv

这适用于我的 ubuntu 14.04，我认为它也应该适用于 Mac。

您可以在此链接中找到详细说明，其中我展示了如何在 Anaconda 中安装 OpenCV。
