从Python virtualenv运行OpenCV [英] Running OpenCV from a Python virtualenv

问题描述

我正在尝试在Ubuntu Server 12.04上的virtualenv中安装OpenCV.我发现讨论此问题的线程但没有从中提取任何信息.

I'm trying to install OpenCV within a virtualenv on my Ubuntu Server 12.04. I found a thread discussing this but managed to extract no information from it.

我尝试使用pip install pyopencv，但失败了.

I tried using pip install pyopencv but it failed.

error: command 'gcc' failed with exit status 1

此错误仅在我第二次运行pip install时发生.如果删除剩余的build/文件夹，则会出现此错误.

This error only occurs the second time I run pip install. If I delete the remainging build/ folder I get this error.

-- Configuring incomplete, errors occurred!

Configuring PyOpenCV via CMake...

Error: error occurred while running CMake to configure PyOpenCV.

You may want to manually configure PyOpenCV by running cmake's tools:

    mkdir build

    cd build

    cmake-gui ..    OR    cmake ..

    cd ..

----------------------------------------
Command python setup.py egg_info failed with error code 255

我至少安装了以下apt软件包.

I have at least the following apt packages installed.

build-essential
uuid-dev
python-dev
python-pip
libpq-dev
cmake
libboost-dev
libcv-dev
libcvaux-dev
libboost-python-dev
libboost1.48-dev

如何在我的virtualenv中安装OpenCV?

How can I install OpenCV within my virtualenv?

推荐答案

启动virtualenv并遵循以下指南:

Fired up a virtualenv and followed this guide: http://www.samontab.com/web/2011/06/installing-opencv-2-2-in-ubuntu-11-04/ , up until manipulating and copying the cv shared objects. Instead, I copied cv.so (from my OpenCV-2.2.0/lib directory) to my virtualenv site-packages (eg. env/lib/python2.7/site-packages/). Once cv.so was in my environment, I was able to import cv within python.
