使用 --no-site-packages 在 vi​​rtualenv 中安装 pyopencv

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 包 python-opencv，但我不知道如何使用 --no-site-packages 将它安装到 virtualenv 中（可能符号链接可以工作，但它很难看...... )。

Answer 1

我认为你必须先安装 openCV 才能构建 python 包装器。

Answer 2

将这两行添加到 /etc/bash.bashrc（或仅在命令提示符下运行）修复问题。

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

也可以按照这里的指令：https://github.com/ingenuitas/SimpleCV#installation

Answer 3

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 4

sudo apt-get build-dep python-opencv

实际上不会安装 python-opencv，但会安装 pyopencv 所依赖的非 Python 包。我发现 apt-get build-dep 是在 virtualenvs 中使用 pip 的绝佳补充。

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
