javascript - React-Native:期望一个字符串或类/函数，但得到:对象

Question

对于我的 react native 应用程序，我得到

Element type is invalid: expected a string (for built-in components) or a class/function(for composite components) but got: object

应用程序/index.js:

import React, { Component } from 'react';
import EStyleSheet from 'react-native-extended-stylesheet';
import { Provider } from 'react-redux';

import Navigator from './config/routes';
import { AlertProvider } from './redux/components/Alert';
import store from './config/stores';


EStyleSheet.build({
    $primaryBlue: '#4F6D7A',
    $primaryOrange: '#D57A66',
    $primaryGreen: '#00BD9D',
    $primaryPurple: '#9E768F',

    $white: '#FFFFFF',
    $lightGray: '#F0F0F0',
    $border: '#E2E2E2',
    $inputText: '#797979',
    $darkText: '#343434',
});

export default () => (
    <Provider store={store}>
        <AlertProvider>
            <Navigator onNavigationStateChange={null} />
        </AlertProvider>
    </Provider>
);

index.android.js 和index.ios.js:

import App from './app/index';
import React, { Component } from 'react';
import { AppRegistry } from 'react-native';

AppRegistry.registerComponent("TestApp", App);

我尝试删除 Provider、AlertProvider 和 Navigator 标记并添加 View 标记，只是为了看看是否仍然会收到错误，但我收到了相同的错误。

我做错了什么？

尝试注册您的根组件

AppRegistry.registerComponent("TestApp", () => App);
