c++ - Mac 中 Electron 中的 native C++ 插件出现问题

Question

我正在编写代码以从 Electron 加载 c++ 动态库。在 Mac 中尝试时出现以下错误:

dyld:找不到符号:__ZN15FcDrive2Library13InitDrive2LibEv

我的 binding.gyp 文件如下所示:

它在Windows中工作。在 Mac 中，我也尝试过重新安装节点模块和 Electron 重建。它们都不适合我。除了 native .node 模块外，dylib 已成功复制。不知道为什么会出现此链接错误

没关系。我意识到需要在 binding.gyp 中添加 link_dependencies 标签。 dylib 也需要复制到项目的根目录。
