问题描述
试图在Mac OSX上使用适用于python的opencv-Mavericks，但在从python导入cv时仍未找到libjpeg.8.dylib的映像
Trying to get opencv for python working on Mac OSX - Mavericks but keep getting an image not found for libjpeg.8.dylib when doing import cv from python
(最近从Mountain Lion更新)
(Recently updated from Mountain Lion)
这就是我所做的:
1. brew tap homebrew/science
2. brew install opencv
3. python
4. import cv
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/Cellar/opencv/2.4.9/lib/python2.7/site-packages/cv.py", line 1, in <module>
from cv2.cv import *
ImportError: dlopen(/usr/local/Cellar/opencv/2.4.9/lib/python2.7/site-packages/cv2.so, 2): Library not loaded: /usr/local/lib/libjpeg.8.dylib
Referenced from: /usr/local/Cellar/opencv/2.4.9/lib/libopencv_highgui.2.4.dylib
Reason: image not found
- 我寻找了libjpeg.8.dylib并在
/usr/local/Cellar/jpeg/8d/lib/中找到了它，显然，它不在libopencv_highgui.2.4.dylib所寻找的位置.
- I looked for libjpeg.8.dylib and found it in
/usr/local/Cellar/jpeg/8d/lib/which, apparently, is not where libopencv_highgui.2.4.dylib is looking.
我对Mac OS和Homebrew有点陌生.谁能解释如何解决此错误并使opencv运行?我已经预装了Mac随附的python，而它们是由自制软件安装的.
I'm a bit new to Mac OS and homebrew. Could anyone explain how to resolve this error and get opencv running? I have the python that comes preinstalled with Mac and them python installed by homebrew.
谢谢.
推荐答案
一种快速而又肮脏的解决方案是在/usr/local/lib文件夹中建立一个指向libjpeg.8.dylib实际位置的符号链接. ，就像这样:
The quick and dirty solution for this is to make a symlink inside of the /usr/local/lib folder pointing to the actual location of libjpeg.8.dylib, like this:
$ sudo ln -s /usr/local/Cellar/jpeg/8d/lib/libjpeg.8.dylib /usr/local/lib/libjpeg.8.dylib
问题是opencv和python期望libjpeg.8.dylib在/usr/local/lib/中，但是自制软件将其安装在/usr/local/Cellar/中，因此令人讨厌的错误.
The problem is opencv and python expect libjpeg.8.dylib to be in /usr/local/lib/ but homebrew installs it in /usr/local/Cellar/, hence annoying error.
