错误代码:React Native 0.56 for Android上的500 [英] error code: 500 on react native 0.56 for android
问题描述
我的项目是一个新的空反应本机项目. 一切在构建时都很酷,但是在android设备上,我每次都遇到红色的错误500"屏幕. 我已经尝试过以下代码:
my project is a new empty react native project. everything is cool at the time of build, but on android device I face the red "error 500" screen every time. I've tried this code:
yarn remove babel-preset-react-native
yarn add babel-preset-react-native@2.1.0
到目前为止没有任何改变!
no change so far!
我已尝试将本机的React降级为55.4-不变! 清洁渔获物-不变! 顺便说一下,这是我的App.js:
I've tried to downgrade the react native to 55.4 - no change! Cleaning the catch - no change! Here is my App.js by the way:
import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View} from 'react-native';
const instructions = Platform.select({
ios: 'Press Cmd+R to reload,\n' + 'Cmd+D or shake for dev menu',
android:
'Double tap R on your keyboard to reload,\n' +
'Shake or press menu button for dev menu',
});
type Props = {};
export default class App extends Component<Props> {
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>Welcome to React Native!</Text>
<Text style={styles.instructions}>To get started, edit App.js</Text>
<Text style={styles.instructions}>{instructions}</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
index.js:
import {AppRegistry} from 'react-native';
import App from './App';
import {name as appName} from './app.json';
AppRegistry.registerComponent(appName, () => App);
这是我的package.json:
and here is my package.json:
{
"name": "app",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest"
},
"dependencies": {
"react": "16.4.1",
"react-native": "0.56.0"
},
"devDependencies": {
"babel-jest": "23.4.2",
"babel-preset-react-native": "5",
"jest": "23.5.0",
"react-test-renderer": "16.4.1"
},
"jest": {
"preset": "react-native"
}
}
