Question

我正在尝试通过brew安装opencv，

但向我展示了以下错误。

我知道我应该点击“brew tap homebrew / homebrew-science”

但它不起作用。

有什么想法，或者我应该通过什么命令显示哪些信息来快速解决问题。

感谢〜

如果我尝试通过教程http://tilomitra.com/opencv-on-mac-osx/手动制作我会在make -j8

之后看到错误

我最近遇到了使用brew构建OpenCV的类似问题。核心问题是OpenCV在构建ffmpeg时无法正常构建（如果还安装了ffmpeg，它会尝试这样做。）

正如建议的here，可以通过使用以下brew命令来构建OpenCV来解决问题，OpenCV强制构建环境的替代版本（brew的顶级troubleshooting suggestions之一）：< / p>

brew install opencv --env=std

希望这也适合你！

无法在mac osx上使用brew或make安装opencv
