Gobot OpenCV 失败

Question

我正在尝试从 GoBot Go Lang OpenCV运行 OpenCV 测试应用程序。我试图运行该页面中给出的示例代码，但得到的只是一个错误：

我究竟做错了什么？我之前已经安装并运行过 C++ OpenCV

跟进评论；我给了 gobot 另一个示例opencv_face_detect，它对我有用。尽管您发布的示例链接似乎有问题/已过时。这是在 OS X 10.11.5 和 go1.6.2 darwin/amd64 上。这是我做的步骤；安装opencv；brew tap homebrew/science && brew install opencv安装gobot和go-opencv；去获取 github.com/hybridgroup/gobot && 去获取 github.com/lazywei/go-opencv运行位于“github.com/hybridgroup/gobot/examples”的 face_detect 示例，不要忘记微笑！去运行 opencv_face_detect.go
