这个错误发生在我的 Metro-bundler 加载 100% 之后(并且在 bundler 控制台屏幕上没有发生错误).

This error happens after my metro-bundler loads 100% ( and no error happens on the bundler console screen ).

感谢所有提供帮助的人！

Thanks for everyone who helps!

推荐答案

就我而言，问题在于 react-native-device-info.

In my case, the problem was with react-native-device-info.

在您的 app/build.gradle 依赖项中试试这个:

Try this in your app/build.gradle dependencies:

dependencies {
   ...
   implementation(project(':react-native-device-info')) {
      exclude group: 'com.google.android.gms'
   }
}

它对我有用.
