Mac 中我在 Electron 中使用本机 C++ 插件的问题

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 引用自：/Users/nikhell/Documents/Codelathe/Workspace/cl-fc-client/electron-drive-client/build/Release/electronToCppBridge.node 预计在：平面命名空间

我的 binding.gyp 文件如下所示：

它正在 windows 工作。在 Mac 中，我尝试重新安装节点模块和电子重建。 None 其中对我有用。除了本机 .node 模块之外，dylib 已成功复制。不知道为什么会出现这个 link 错误

Answer 1

没关系。我意识到 link_dependencies 标签需要添加到 binding.gyp 中。此外，dylib 需要复制到项目的根目录。
