我正在尝试安装 node opencv ，我在 Mac 上运行小牛。我运行“npm install opencv”并尝试了很多方法来解决这个问题，但无法弄清楚。这是我的错误：还有一堆警告，但这是失败之前的错误：

当我运行 node-gyp configure 或 node-gyp rebuild 时发生类似的错误我试图在这里获得帮助：https ://github.com/joyent/node/issues/3113 但它没有帮助，我仍然得到 gyp 错误

运行 npm install opencv 时：这是整个输出

npm WARN package.json make@0.0.0 No repository field.

npm http 304 https://registry.npmjs.org/opencv

你的错误是这样的：

../src/FaceRecognizer.cc:64:76: error: too many arguments to function call,
      expected at most 4, have 5
  ...f = cv::createLBPHFaceRecognizer(1, 8, 8, 8, 80.0);

因此，您正在编译的 OpenCV 版本与节点模块使用的版本不同。

在这个 opencv 提交createLBPHFaceRecognizer中添加了第五个参数，所以看起来你至少需要 OpenCV ，而你错误提到。v2.4.3v2.4.0

您应该通过运行确保您的brew安装是最新的brew update，然后brew upgrade opencv从 homebrew 中提取最新的 OpenCV，它看起来是v2.4.7.1.

嗯，在我的情况下是不一样的，但你可以尝试以下。这是我在 Mac OS X 上修复 OpenCV 和 npm opencv 的方法：

  1. 安装自制软件ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

  2. 安装opencvbrew install homebrew/science/opencv

  3. 安装 pkg 配置：brew install pkg-config

  4. 通过运行查找名为opencv.pc的文件的位置mdfind -name opencv.pc

  5. 运行nano .bash_profile并将第 4 步中找到的路径添加到您的 Bash 环境变量中。保存存档。关闭并重新启动终端。

我的 Mac 中的示例：

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/Cellar/opencv/2.4.12_2/lib/pkgconfig
export PKG_CONFIG_PATH

env | grep PKG_CONFIG_PATH您可以通过在终端中运行来检查是否已配置。
