我认为打包后路径可能是错误的。您应该尝试在应用中执行 console.log（app.getAppPath（））; （例如，发送至渲染器，写入日志文件等），以进行仔细检查。如果它指向预期的路径。

I think the path could be wrong after packaging. You should try to do a console.log(app.getAppPath()); (e.g. send to renderer, write to a log file etc.) in your app to double check if it is pointing to the expected path.
