此错误仅在我第二次运行 pip install 时发生.如果我删除剩余的 build/ 文件夹，我会收到此错误.
This error only occurs the second time I run pip install. If I delete the remainging build/ folder I get this error.

Configuring 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 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 并遵循本指南:http://www.samontab.com/web/2011/06/installing-opencv-2-2-in-ubuntu-11-04/ , 直到操作和复制 cv 共享对象.相反，我将 cv.so(从我的 OpenCV-2.2.0/lib 目录)复制到我的 virtualenv 站点包(例如 env/lib/python2.7/site-packages/).一旦 cv.so 在我的环境中，我就可以在 python 中导入 cv.
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.
