【问题描述】：
我的 react native 应用程序在调试时工作，但在发布时崩溃。
我目前正在运行 RN：
- react-native-cli: 2.0.1
- 反应原生：0.46.4
我已经尝试打开 proguard。
def enableProguardInReleaseBuilds = true
我开始了一个全新的项目并添加了所有源代码，但问题仍然存在。
如何查找导致此错误的原因：
对象作为 React 子对象无效（发现：对象与键 {$$typeof, type, key, ref, props, _owner}）。

好吧，ReactNative 通常会在尝试渲染既不是组件也不是基本类型（如字符串、整数等）的东西时引发该异常。可能发生的情况是，在发布模式下，您会收到一个复杂的对象，而不是您在调试模式下收到的简单对象。您能否添加有关如何生成发布部署的信息？谢谢。

有什么解决办法吗？我有同样的问题。
