无法运行require('opencv4nodejs')

Question

我用的是macOS蒙特利12.2.1，苹果M1。在项目目录中，我通过以下脚本代码安装了opencv-build和opencv4nodejs：

"scripts": { "postinstall": "npm i opencv-build && npm i opencv4nodejs" }

当我运行cv = require('opencv4nodejs')时，我收到了这条错误消息，我无法理解它。如何正确运行此代码？

/usr/local/bin/node /Users/david/Desktop/project2/main.js
/Users/david/Desktop/project2/node_modules/opencv4nodejs/lib/cv.js:47
    throw err
    ^

使用Node14.18.1，然后卸载opencv4nodejs。

运行export CXXFLAGS="-std=c++14 -Wno-c++11-narrowing"

运行npm install opencv4nodejs
