我在OSX上使用自制软件安装opencv3(EI Captain),
brew install opencv3 --with-contrib --with-python3 --HEAD
并发生错误:

Error: No such file or directory - /private/tmp/opencv3-20170330-14255-bxsn05/3rdparty/ippicv/downloader.cmake
你们可以帮我找出解决方法吗?
答案 0 :(得分:19)
我做brew edit opencv3
,然后评论以下一行
inreplace buildpath/"3rdparty/ippicv/downloader.cmake",
"${OPENCV_ICV_PLATFORM}-${OPENCV_ICV_PACKAGE_HASH}",
"${OPENCV_ICV_PLATFORM}"
然后您可以使用--HEAD
opencv存储库修复了一些问题,也删除了文件3rdparty/ippicv/downloader.cmake
,因此无需再修补它。但他们没有发布新版本,因此要安装--with-contrib
,您必须使用--HEAD
进行安装,但要禁用文件补丁3rdparty/ippicv/downloader.cmake

我遇到了同样的问题。我通过运行brew install opencv3 --with-contrib --with-python3
我认为发生的事情是人们更新了回购邮件中的 ../ 3rdparty / ippicv 文件夹,以致 downloader.cmake 文件不再存在,但他们还没有更新酿造配方。
没有--HEAD
的brew安装将构建opencv3.2.0,这对我来说已经足够了。

当我搜索OpenCV java问题时,这是第一个结果。如果有人使用OpenCV Java,那么发布我的答案就会对他们有用。
我正在关注这篇文章:https://opencv-java-tutorials.readthedocs.io/en/latest/01-installing-opencv-for-java.html
酿造自制土豆/科学 brew install opencv3 --HEAD --with-contrib --with-java我尝试从上面的命令中删除--Head,并且我能够成功安装它。
brew install opencv3 --with-contrib --with-java
根据这篇文章:https://github.com/Homebrew/homebrew-science/issues/5498
答案 3 :(得分:1)
我已通过以下方式解决了该问题:
$ brew edit opencv3
找到以下代码块并注释所有4行:
if build.with?("python3") && build.with?("python")
# Opencv3 Does not support building both Python 2 and 3 versions
odie "opencv3: Does not support building both Python 2 and 3 wrappers"
end
最后使用brew install命令安装:
$ brew install opencv3 --with-contrib --with-python3
