【问题描述】：
在设备上以发布模式运行 React Native 应用程序时，我在启动时遇到崩溃（调试模式工作正常）。主要错误似乎是：
AndroidRuntime：java.lang.RuntimeException：无法从资产“index.android.bundle”加载脚本。确保您的捆绑包已正确打包，或者您正在运行打包服务器。
我已经找到了关于这个错误的各种线程，但是有关于旧版本的，并且提供的解决方案都没有工作。
日志如下：

知道可能是什么问题吗？
编辑：我无法将 gradle 构建工具从 3.2.0 降级到 3.1.4，因为 Firebase 模块需要 3.2.0。
【问题讨论】：
-
Tareq，这个问题中的解决方案是针对调试版本的，而在我的情况下，它是仅在发布模式下发生的崩溃。无论如何，我已经尝试在那里应用一些解决方案，但它们都不起作用（可能是因为它们适用于旧版本的 RN）。
-
你能分享你的 package.json 文件吗？您还使用 Expo 或 ignite 进行项目生成吗？
-
我不使用 Expo，它是一个被弹出的应用程序。包文件在那里：github.com/laurent22/joplin/blob/master/ReactNativeClient/…
