React Native Error：元素类型无效

Question

I need some help looking for where to start with this error I'm getting. Nimbus is the name of my app but I'm not sure what it means when it says check the render method of 'Nimbus' . Which render method? I have a functional component at app/index.js called Nimbus but obviously that doesn't render anything just returns a component.

I've checked similar error messages for RN on here and most people are just forgetting to export a component properly but I've checked my components and all are being exported correctly from what I can tell. The repo is below if you want to take a look at my project structure, etc. There are only a few files right now. Sorry I can't provide more information that's all I've got right now.

Answer 1

Because the AppContainer is a default export:

export default class AppContainer ...

And you proxy it from the containers/index.js like this:

export { AppContainer } from  './App/AppContainer'

This tries to import a named export called AppContainer . Instead, you'll need to import the default export explicitly:

export { default as AppContainer } from  './App/AppContainer'

Answer 2

in your index.js you need to import component.

change following.

import { NimbusNavigator } from  './Navigator/NimbusNavigator'
import { SplashContainer } from './Splash/SplashContainer'
import { AppContainer } from  './App/AppContainer'
