React-Native type is invalid -- expected a string

问题

I'm starting with react native and I find the next mistake, I'm a little disoriented.

From App.js I import the component Home.js, but I get the following error:

### ERROR #################

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components)
but got: %s.%s%s, undefined, You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

#### App.js #############

import React, { Component } from 'react';
import { StyleSheet, Text, View, TextInput, TouchableOpacity } from 'react-native';

import { Home } from './componentes/Home';

export default class App extends Component {

render(){
return(



);
}

### ./componentes/Home.js ###########

import React, { Component } from 'react';
import { StyleSheet, Text, View, TextInput, TouchableOpacity } from 'react-native';

export default class Home extends Component{
render() {
return (
Home
);
}
}

得分: 1

只需在你的 App.js 中修改导入 Home 组件的方式,从:

import { Home } from './componentes/Home';

改为:

import Home from './componentes/Home';

希望能帮助你,有疑问请随时提问。

英文:

Just in your App.js change your way of importing Home to ,

import  Home  from './componentes/Home';

AND NOT THE ONE BELOW

import { Home } from './componentes/Home';

hope it helps , feel free for doubts
