在Mac OS X上使用pip安装pyopencv

Question

我正尝试在OS X Mountain Lion中使用pip安装pyopencv，并且导入setuptools失败。以下是我的工作。 setuptools中的“Library”是什么？我以前没有见过。我已经通过自制软件和其他东西安装了opencv。在pyopencv的doucmentation，它不能解释与PIP只安装源安装，

编辑：我发现setuptools的来源有图书馆和扩展（https://bitbucket.org/pypa/setuptools/src/27df3c725f9696ba730456f3f444cc2fb5271d4b/setuptools/extension.py?at=default），但我不知道为什么它不承认。

我setuptools的verison是1.1.6

(img2)appleparan@LiamMac src $ pip install setuptools --upgrade 
Requirement already up-to-date: setuptools in /Users/appleparan/.virtualenvs/img2/lib/python2.7/site-packages/setuptools-1.1.6-py2.7.egg

Answer 1

在最新版本的setuptools的，Library是extension.py内。 pyopencv应该输入Library为setuptools.extension.Library而不是setuptools.Library。

Answer 2

变化

from setuptools import setup, find_packages, Extension, Library 

到

from setuptools import * 
from setuptools.extension import * 

Answer 3

可以打印python运行Python解释器，然后打印以下内部蟒蛇：

进口SYS
sys.path的

在输出中寻找类似于/Library/Python/2.7/site-packages的行。 打印exit()退出python解释器。

在命令行问题命令：cd /Library/Python/2.7/site-packages和列表文件与ls命令。寻找文件'cv.py'和'cv2.so'。他们应该在那里。然后参考~/.bash_profile文件发布命令cat ~/.bash_profile找到您的PYTHONPATH：应该有类似于export PYTHONPATH=/usr/local/lib/python2.7/site-packages的行。发出命令cd /usr/local/lib/python2.7/site-packages跳转到该文件夹​​。现在

你可以为cv2.so和cv.py发出命令创建符号链接： sudo ln -s /usr/local/lib/python2.7/site-packages/cv.py /Library/Python/2.7/site-packages/cv.py和 sudo ln -s /usr/local/lib/python2.7/site-packages/cv2.so /Library/Python/2.7/site-packages/cv2.so。
