如何在React Native中使用index.js代替（index.ios.js，index.android.js）进行跨平台应用？

问题描述：

感谢您从现在开始的答案，

Thanks for the answers from now,

我是 React Native 的新手，我想创建一个跨平台的应用程序我创建了index.js：

I am a newbie in React Native, I want to make a cross-platform app so I created index.js:

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

class ReactApp extends Component {

    render() {
        return (
            <View><Text>Hello world</Text></View>
        );
    }
}

module.exports = ReactApp;

然后我从index.ios.js和index.android.js这样导入了index.js ：

Then I imported index.js from both index.ios.js and index.android.js like this:

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

AppRegistry.registerComponent('ReactApp', () => ReactApp);

我想在此之后它应该可以工作，但我得到这个
错误：

I think after this it should work but I get this error:

答

React v0之后.49，你不需要 index.ios.js 和 index.android.js 。您只需要 index.js ：

After React v0.49, you don't need index.ios.js and index.android.js. You only need the index.js:

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

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

（用你的名字替换 appMobile app）

(replace appMobile with the name of your app)

从现在开始，新项目只有一个入口点（index.js）

New projects have a single entry-point (index.js) from now on
