升级OpenCV brew公式：Python无法正确加载

cgat 发表于 Dev

我正在尝试更新最新的opencv公式（在撰写本文时，此公式将安装opencv 2.4.7）以构建最新版本的opencv（2.4.8）。

我做的第一件事是brew edit opencv，并将URL更改为“ https://github.com/Itseez/opencv/archive/2.4.8.tar.gz ”并更新校验和。我预料到我可能不得不处理一些固有的问题，但是运行公式时似乎会出现该问题。

具体来说，当我运行brew upgrade opencv（或取消链接并运行brew install opencv）时，会收到以下消息：

==> Downloading https://github.com/Itseez/opencv/archive/2.4.8.tar.gz
Already downloaded: /Library/Caches/Homebrew/opencv-2.4.8.tar.gz

Python似乎没有被加载。我也对弃用警告感到困惑；我发现的一切都表明python公式是我应该使用的公式。这个判断链接的depends_on :python相关性似乎像它应该工作（当我与以前2.4.7.1公式尝试了明显所做的那样）。

供参考，这是我的环境变量：
