我一直在尝试使用 npm install opencv4nodejs 命令安装 opencv4nodejs 包。但不幸的是，下面的内容被抛出。进行了一些研究并进行了一些调整，但所有这些都不起作用。

以下是错误：

【解决方案1】：

试试这个

$ export OPENCV4NODEJS_DISABLE_AUTOBUILD=1

$ npm i opencv4nodejs

【解决方案2】：

好的，所以我能够完全安装 opencv4nodejs 工作。我需要将节点从版本 16 降级到版本 14 并进行一点编译器选项挖掘！

当前设置

macOS Big Sur v11.6.1
Homebrew 3.3.2
opencv 4.5.3_2
节点 v14.18.1

节点安装（使用 Homebrew）
brew install node@14

opencv 安装（使用 Homebrew）
冲泡安装opencv

opencv4nodejs 安装（带有节点安装程序）

在安装之前设置以下两个编译器标志
export CXXFLAGS="-std=c++14 -Wno-c++11-narrowing"
在您设置了上述环境变量的同一终端中运行安装
npm install opencv4nodejs

【解决方案3】：

第 1 步：使用以下命令在您的 Mac 上找到 opencv 库位置

find / -name "OpenCVConfig.cmake"

第 2 步：为您提供以下路径

/opt/homebrew/Cellar/opencv/4.5.2_4/lib

第 3 步：打开 zshrc 文件

open ~/.zshrc

第 4 步：将以下行放入 zshrc 文件中

export OPENCV_LIB_DIR="/opt/homebrew/Cellar/opencv/4.5.2_4/lib"

第 5 步：保存并关闭 zshrc 文件第 6 步：执行以下命令

source ~/.zshrc

第 7 步：现在尝试执行 npm i opencv4nodejs

干杯！
