当我尝试在另一台计算机上运行打包的应用程序时，出现以下错误：
dlopen(/Users/holle/Downloads/Repeato.app/Contents/Resources/app/node_modules/opencv4nodejs/build/Release/opencv4nodejs.node, 1): Library not loaded: /usr/local/opt/gstreamer/lib/libgstbase-1.0.0.dylib

此处记录了相同的问题，但是没有提供解决方案： https://github.com/electron-userland/electron-builder/issues/2738
我正在使用电子包装机进行构建，并使用命令npm run dist进行构建。 我在这里创建了该软件的精简版本： https://github.com/stoefln/opencv4nodejs-test
出于简化原因：这是package.json：
