Require cycles are allowed, but can result in uninitialized values. Consider refactoring to remove the need for a cycle. WARN Require cycle: src/store/index.js -> src/reducers/index.js -> src/reducers/NavigationReducer.js -> src/router/rootNavigation/navigationConfiguration.js -> src/router/caStackNavigation/CAStackNavigation.js -> src/router/caStackNavigation/navigationConfiguration.js -> src/screens/AddScreen.js -> src/components/jiedai/TouxiangItem.js -> src/components/common/index.js -> src/components/common/Container.js -> src/utils/AppWatermarkView.js -> src/store/index.js

Require cycles are allowed, but can result in uninitialized values. Consider refactoring to remove the need for a cycle. ERROR Invariant Violation: ReactClassInterface: You are attempting to define UNSAFE_componentWillMount on your component more than once. This conflict may be due to a mixin. ERROR Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect. This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native.

I have solved the problem by upgrading the create-react-class package from 15.6.2 to 15.6.3 (or higher)
