Question

我正在尝试在OS X Mountain Lion中使用pip安装pyopencv，但导致setuptools失败。以下是我的工作。 setuptools中的“库”是什么？我之前没见过。我已经通过自制软件和其他东西安装了opencv。在pyopencv的doucmentation中，它没有解释使用pip仅源安装的安装，

编辑：我发现setuptools源代码库和扩展名（https://bitbucket.org/pypa/setuptools/src/27df3c725f9696ba730456f3f444cc2fb5271d4b/setuptools/extension.py?at=default）但我不知道为什么它不能识别。

我的setuptools'版权是1.1.6

Answer 1

在最新版本的setuptools中，Library位于extension.py内。 pyopencv应将Library导入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

您可以打印python来运行python解释器，然后在python中打印以下内容：

import sys
sys.path中

在输出中查找与/Library/Python/2.7/site-packages类似的行。打印exit()以退出python解释器。

在命令行问题命令中：cd /Library/Python/2.7/site-packages并使用ls命令列出文件。查找文件'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：应该有与export PYTHONPATH=/usr/local/lib/python2.7/site-packages类似的行。发出命令cd /usr/local/lib/python2.7/site-packages以跳转到该文件夹。

现在您可以为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。
