可以在Mac Mountain Lion上的python virtualenv中安装OpenCV [英] can OpenCV be installed in python virtualenv on Mac Mountain Lion

问题描述

我在Mac上使用virtualenv安装了Numpy和Scipy.

I have install Numpy and Scipy with virtualenv on my mac.

今天，我想在virtualenv下安装Opencv. 我尝试:

Today, I want to installed Opencv under virtualenv. I try:

pip install pyopencv

终端返回:

找不到满足pyopencv要求的版本(来自版本:2.0.wr1.0.1-demo，2.0.wr1.0.1、2.0.wr1.1.0、2.1.0.wr1.0.0、2.1.0.wr1 .0.1、2.1.0.wr1.0.2、2.1.0.wr1.1.0、2.1.0.wr1.2.0、2.1.0.wr1.2.0-demo，2.1.0.wr1.2.0) 打扫干净... 没有与pyopencv版本匹配的发行版

Could not find a version that satisfies the requirement pyopencv (from versions: 2.0.wr1.0.1-demo, 2.0.wr1.0.1, 2.0.wr1.1.0, 2.1.0.wr1.0.0, 2.1.0.wr1.0.1, 2.1.0.wr1.0.2, 2.1.0.wr1.1.0, 2.1.0.wr1.2.0, 2.1.0.wr1.2.0-demo, 2.1.0.wr1.2.0) Cleaning up... No distributions matching the version for pyopencv

推荐答案

我遇到了同样的问题，我无法以正确的方式使用pip在virtualenv中安装OpenCV.但是，这就是我所做的:

I had the same problem, I couldn't get OpenCV installed in virtualenv using pip in the proper way. However this is what I have done:

1. 使用Homebrew(以及所有依赖项(例如numpy))安装OpenCV和Python
2. 然后我安装了virtualenv并使用numpy创建了一个新的虚拟环境.

3. 最后，我所做的是将文件夹从正常" python安装符号链接到virtualenv:

1. Install OpenCV and Python using Homebrew (and all depenencies such as numpy)
2. Then I installed virtualenv and create a new virtual environment with numpy.

3. Finally what I did was symlinked the folder from the "normal" python installation to the virtualenv:

$ ln -s /usr/local/lib/python2.7/site-packages/cv2.so /usr/local/lib/python2.7/site-packages/cv.py ~/envs/lib/python2.7/site-packages

因此，当我启动virtualenv时，我有可用的cv2:

So when I launch the virtualenv I have cv2 available:

(virtualenv)localhost:~ juan$ python
Python 2.7.3 (default, Mar 18 2013, 11:14:52) 
[GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.27)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2
<module 'cv2' from '/Users/juan/envs/lib/python2.7/site-packages/cv2.so'>

在MacOSX 10.8.5上，我使用Python 2.7.3，OpenCV 2.4.4a，virtualenv 1.10.1的方式

By the way I am using Python 2.7.3, OpenCV 2.4.4a, virtualenv 1.10.1 on MacOSX 10.8.5
