Я попытался запустить реактивный симулятор.
Однако эта ошибка появилась в симуляторе:
Failed to load bundle(http://localhost:8081/index.bundle?
platform=ios&dev=true&minify=false)
with error:(/Users/sugawarasyuta/Desktop/albums/index.js:
Cannot read property 'bindings' of null(null))
Я дважды проверил свой синтаксис кода. Но я чувствую, что это не об этом. Вы знаете, как решить эту ошибку?
Вот мои файлы:
index.js
import React from 'react';
import { AppRegistry,View } from 'react-native';
import Header from './src/components/header';
import AlbumList from './src/components/AlbumList';
//Create a component
const App = () => (
<View>
<Header headerText= {'albums'} />
<AlbumList />
</View>
);
AppRegistry.registerComponent('albums', () => App );
AlbumList.js
import React,{Component}from 'react';
import {View, Text} from 'react-native';
import axios from 'axios';
class AlbumList extends Component {
componentWillMount(){
axios.get('https://rallycoding.herokuapp.com/api/music_albums')
.then(response => console.log(response));
}
render(){
return(
<View>
<Text>AlbumList!!!</Text>
</View>
);
}
}
export default AlbumList;
Это терминальные утверждения:

Это мой package.json. Правильны ли эти зависимости?

Я обновил "babel-preset-react-native" с "4.0.0" до "^5.0.1" и появилась еще одна ошибка:

Я чувствую, что это происходит не из-за синтаксической ошибки, а из-за зависимости. Знаете ли вы, как я могу это исправить?
