使用Homebrew安装OpenCV3:opencv没有定义头 [英] Installing OpenCV3 with Homebrew: No head is defined for opencv
问题描述
我在安装OpenCV3时遇到了我遇到的错误...
I am having trouble installing OpenCV3 with the error I have...
opencv没有定义头
No head is defined for opencv
我在互联网上找不到任何解决方案. 我将这些网站用作参考:
I have not found any solution to on the internet. I used these websites as references:
https://www.learnopencv.com/install-opencv3-on- macos/
我遵循的确切步骤是:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
echo "# Homebrew" >> ~/.bash_profile
echo "export PATH=/usr/local/bin:$PATH" >> ~/.bash_profile
source ~/.bash_profile
brew install python python3
brew link python
brew link python3
然后我尝试查看我拥有的版本，然后运行:
Then I tried to see what versions I had so I ran:
which python2
which python3
仅存在python3的文件路径，因此我决定显式安装python2:
Only a file path for python3 existed so I decided to explicitly install python2:
brew install python2
然后它说，当我尝试链接它时，它已经被链接了(不确定是否与问题相关，但是可能是这样):
Then it said it was already linked when I tried to link it (not sure if this is relevant to the issue, but it may be):
brew link python2
返回:
警告:已链接:/usr/local/Cellar/python@2/2.7.14_3至 重新链接:brew取消链接python @ 2&&酿造链接python @ 2
Warning: Already linked: /usr/local/Cellar/python@2/2.7.14_3 To relink: brew unlink python@2 && brew link python@2
然后我再次检查which一切都很好，并且现在有python2和python3.
Then I checked it was all good with which again and python2 and python3 were now there.
python2 --version ===> Python 2.7.14
python3 --version ===> Python 3.6.4
由于python(我认为)都很好，所以我尝试使用以下命令安装OpenCV3w:
The since the pythons (I think) are all good, I tried installing OpenCV3w with:
brew install opencv3 --with-contrib --with-python3 --HEAD
但错误是
错误:没有为opencv定义头
Error: No head is defined for opencv
我 需要 是头吗?到底怎么了?
Do I NEED the head? What's wrong with it anyway?
P.S.(不确定).
brew info opencv3

推荐答案
编译OpenCV可能很困难，甚至在MacOS上也更难.自制软件通常可以缓解这种情况，但是目前opencv的食谱是一个好的开始.
Compiling OpenCV can be hard, and even harderon a MacOS. Homebrew alleviates this often, but the current recipe for opencv is a good start.
但是，我遇到了问题，主要是它可以针对python2进行编译，并且我的所有工具链都位于python3中.因此，我创建了一个新的酒桶来安装依赖tbb 然后是 opencv 的一个.为了最终实现编译，您将不必这么做，我必须删除一些依赖项，尤其是对protobuf的依赖项.
However, I had problems with it, the main being that it would compile against python2 and that I have all my toolchain in python3. So I created a new cask to install a dependence on tbb and then one for opencv. You will not that to achieve compilation to the end, I had to remove some dependencies, and in particular that to protobuf.
为方便起见，您可以克隆/下载存储库并启动此脚本 脚本，它将清理内容并运行安装.欢迎任何评论！
For convenience, you can clone / download the repository and launch this script script which cleans up things and then runs the install. Any comments are welcome!
