陣營母語：元素類型是無效的預期字符串，但有反對

Question

我得到這個錯誤，不知道問題出在哪裏？ 我想給header.js導入index.js

我index.js是：

//for ios application PLACE CODE HERE:::: 

//Import a library to help create a component 
import React from 'react'; 
import { Text , AppRegistry } from 'react-native'; 
import Header from './src/components/header'; 


//Create a component 

const App =() => { 
    return (
    <Header/> 
    ); 
}; 

//Render it to the device 

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

而且header.js：

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

const Header =() => { 
    return <Text>Albums!</Text>; 
}; 

export default Header; 

誰能幫我什麼是我錯了嗎？

按照以下步驟更改您的header.js。

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

class Header extends React.Component { 
    render() { 
    return <Text>Albums!</Text>; 
    } 
} 

export default Header;
