Question

我正在尝试将pyopencv安装到使用--no-site-packages选项创建的virtualenv：

pip install pyopencv

但是我在Ubuntu 10.04.3上遇到以下错误：

CMake Error at CMakeLists.txt:186 (find_package):

Could not find a configuration file for package OpenCV.
Set OpenCV_DIR to the directory containing a CMake configuration file for

OpenCV.  The file will have one of the following names:
  OpenCVConfig.cmake
  opencv-config.cmake

我已经安装了numpy，scipy和OpenCV（libboost-dev libboost-python1.40.0 libboost-python1.40-dev cmake libcv4 libcv-dev libcvaux4 libcvaux-dev）。有什么想法吗？

PS我知道有预先构建的Ubuntu软件包python-opencv，但我不知道如何使用--no-site-packages将它安装到virtualenv中（可能symlink会起作用，但它很丑... ）。

Answer 1

将这两行添加到/etc/bash.bashrc（或者只是在命令提示符下运行）可以解决问题。

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

Answer 2

我认为你必须先安装openCV来构建python包装器。

Answer 3

sudo apt-get build-dep python-opencv

实际上不会安装python-opencv，但它会安装pyopencv依赖的非Python包。我发现apt-get build-dep是在virtualenvs中使用pip的一个很棒的补充。

Answer 4

Pip在您的路径中缺少opencv。

如果您尚未安装opencv，sudo apt-get install opencv将解决此问题。

Answer 5

here, try this, open /etc/ld.so.conf.d/opencv.conf as root with your favourite
editor say gedit and add this line to it /usr/local/lib
Reload configuration files created 
sudo ldconfig
now open /etc/bash.bashrc and add this line 
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
then copy these files as below
sudo cp /usr/local/lib/python2.7/site-packages/cv.so /usr/local/lib/python2.7/dist-packages/cv.so
And then try testing your openCV. HAPPY CODING
