React Native Run-Android不更新修改后的代码 [英] React native run-android do not updating modified code

问题描述

我在Windows PC上使用React native 0.52.0和react-native-cli 2.0.1进行android开发.尽管我进行了所有更改.当我运行react-native run-android时，它会成功构建，但是当我运行它时，会得到默认的react native屏幕.

I am using React native 0.52.0 and react-native-cli 2.0.1 on my Windows PC for android development. Despite all the changes i have made. When I run react-native run-android, it builds successfully but when I run it, I get the default react native screen.

我运行react-native run-android-时的结果

我得到的应用程序

index.js

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

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

app.js

import React from 'react'
import ReactNative, { Text } from 'react-native'

export default const App = () => {
  return (
    <Text>Hello World</Text>
  )
}

当我运行react-native init albums时，它只是创建的index.js文件，没有index.android.js或index.ios.js文件 我在做什么错了?

When i ran react-native init albums, it was just an index.js file that was created, there was no index.android.js or index.ios.js file What am I doing wrong?

推荐答案

假定您在正确的文件夹中，请尝试执行以下操作:

Assuming that you are in the right folder, try to do this:

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

如果您拥有index.android.js，请改为执行此操作:

if you have index.android.js, do this instead:

react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

然后只需执行react-native run-android.

Then just execute react-native run-android.
