javascript - 在 index、js 和 app.js 中 react native 错误

Question

React 有点新手我正在 index.js 和 app.js 中编写以下代码，出现此错误消息。请帮忙

index.js--[错误截图][1]

import { AppRegistry } from 'react-native';
import App from './App';

AppRegistry.registerComponent('albums', () => App);

App.js--

    import React from 'react';
    import { Text } from 'react-native';

const App = () => {

return (

  <Text>HEELLO WORLD</Text>

);
};
export default App;

您可能需要一个文本组件之前的 View 。像这样:

import React from 'react';
import { View, Text } from 'react-native';

const App = () => (
   <View>
     <Text>some text</Text>
   </View>
);

export default App;
