python - 使用 Homebrew 安装 openCV 时遇到问题

Question

我正在运行 mac os x mavericks，我正在尝试使用 Homebrew 安装 openCV 我不确定如何修复它，我应该卸载 Homebrew 和 python，然后再试一次，如果可以，我该如何卸载它们

首先我做了这个 ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install )" 然后这个 brew tap homebrew/science 这是有效的，因为当我再次输入 brew tap homebrew/science 时，我收到了警告:已点击!

但是当我输入 brew info opencv 时，我收到了这个错误 错误:opencv 没有可用的公式 当我尝试 brew install opencv 它显示了这个

Searching formulae...
Searching taps...
mymac:~ user$

这是我运行 brew doctor 时得到的结果

working fine: please don't worry and just ignore them. Thanks!

Warning: Python is installed at /Library/Frameworks/Python.framework

Homebrew only supports building against the System-provided Python or a
brewed Python. In particular, Pythons installed to /Library can interfere
with other software installs.

Warning: /usr/bin occurs before /usr/local/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:

    2to3
    2to3-2.7
    idle
    idle2.7
    pydoc
    pydoc2.7
    python
    python-config
    python2.7
    python2.7-config
    pythonw
    pythonw2.7
    smtpd.py
    smtpd2.7.py

Consider setting your PATH so that /usr/local/bin
occurs before /usr/bin. Here is a one-liner:
    echo export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile

Warning: Your Xcode (6.0.1) is outdated
Please update to Xcode 6.1.
Xcode can be updated from the App Store.

brew doctor 
brew tap homebrew/science

这是我在 linux 上安装的过程。它在过去对我来说很有效:

1. 从 http://opencv.org/downloads.html 下载 OpenCV 2.4.9适用于 Linux/Mac OS 和提取。

2. 在终端中，导航到新提取的目录，并在终端中使用 mkdir build 创建一个名为 build 的新目录。然后cd到build

3. 现在，在终端中输入:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D BUILD_JPEG=ON ..

1. 完成后，在终端中输入 make -j 4 这可能需要一段时间。

2. 现在在终端输入sudo make install

3. 然后 sudo sh -c 'echo "/usr/local/lib">/etc/ld.so.conf.d/opencv.conf' sudo ldconfig

4. 如果成功，您应该能够在 python 提示符下import cv2 而不会出现任何错误。
