node.js - 用于 windows 的 node-opencv

Question

我正在尝试在 windows7 中安装 node-opencv 或 opencv-node 作为 Node 模块。
可以从命令提示符访问 node 和 node-gyp。
设置了 Python 和 env 变量。
我相信 openCV 至少安装到拥有预建库的程度。
但是对于 node-opencv 和 opencv-node 我都得到了同样的错误。

日志文件说的几乎相同，任何帮助表示赞赏!

- 更新，安装 python 2.7.3 后，我现在收到此错误:

我有类似的麻烦。
我的解决方案是以管理员身份启动“VS2015 的开发人员命令提示符”(您需要安装 Visual Studio)。
只有在其中我才能安装opencv(npm i opencv)而不会出错，但会出现警告。
也许，它也会帮助你!
