현재 Android 에뮬레이터 에서 ES6 react-native-webpack-server를 실행 하려고합니다 . 차이점은 업그레이드 package.json하고 build.gradereact을 사용 0.18.0하고 부팅 시이 오류가 발생 한다는 것 입니다. 내가 아는 AppRegistry한 올바르게 가져옵니다. 코드를 주석 처리하더라도이 오류는 여전히 발생합니다. 이것은 문제없이 iOS에서 작동합니다.

내가 뭘 잘못하고 있죠?

편집 : 0.18.0을 지원하는 다른 상용구를 시도한 후에도 동일한 문제가 발생합니다.

---

나는 0.18.1오늘 0.19.0-rc출시 전 버전에서 피어 종속성 문제가 발생 하여 react-native로 업그레이드했습니다 .

질문으로 돌아가서 내가 한 일은

1. cd android
2. sudo ./gradlew clean

그런 다음 작업 디렉토리로 돌아가서 실행하십시오. react-native run-android

업그레이드 후에도 npm을 다시 시작해야합니다.

이것이 당신을 위해 작동하기를 바랍니다.

나는 iOS에서 같은 문제가 있었고 그 원인은 내 index.ios.js 가 잘못 되었다는 것입니다 (내용을 보지 않고 예제 중 하나를 복사하여 붙여 넣었 기 때문에) 모듈 내보내기 선언으로 끝났습니다.

exports.title = ...
exports.description = ...
module.exports = MyRootComponent;

예상 대신

AppRegistry.registerComponent('MyAppName', () => MyRootComponent);

내가 추측하는 index.android.js를 사용하여 Android에서 동일한 문제가 발생할 수 있습니다.

---

한 주 이 문제의 원인은 어디에있을 수 는 플러그인을 설치하고 연결하는 것을 잊지 것이다 .

이 시도:

react-native link

앱을 다시 실행하십시오.

이것이 도움이되기를 바랍니다. 댓글로 알려주세요 . 감사.

---

이 문제를 해결했습니다.

import { AppRegistry } from "react-native";
import App from "./App";
import { name as appName } from "./app.json";  
AppRegistry.registerComponent(appName, () => App);

내 index.js에

이것이 index.js 에 있는지 확인하십시오.

Hopefully this can save someone a headache. I got this error after upgrading my react-native version. Confusingly it only appeared on the android side of things.

My file structure includes an index.ios.js and an index.android.js. Both contain the code:

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

What I had to do was, in android/app/src/main/java/com/{projectName}/MainApplication.java, change index to index.android:

@Override
protected String getJSMainModuleName() {
    return "index.android"; // was "index"
}

Then in app/build/build.gradle, change the entryFile from index.js to index.android.js

project.ext.react = [
    entryFile: "index.android.js" // was index.js"
]

---

I don't know why, but when I move AppRegistry.registerComponent from the index.js file that is included in index.android.js to reside inside index.android.js directly, it seems to work.

---

For me my issue was putting the wrong entry-file when bundling.

I was using App.js as my entry-file, hence the App couldn't find AppRegistry

Correct:

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/

Incorrect:

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

If you are using some of the examples they might not work

Here is my version for scroll view

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 */

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

class AwesomeProject extends Component {
  render() {
    return (
        <View>
          <ScrollView
            ref={(scrollView) => { _scrollView = scrollView; }}
            automaticallyAdjustContentInsets={false}
            onScroll={() => { console.log('onScroll!'); }}
            scrollEventThrottle={200}
            style={styles.scrollView}>
            {THUMBS.map(createThumbRow)}
          </ScrollView>
          <TouchableOpacity
            style={styles.button}
            onPress={() => { _scrollView.scrollTo({y: 0}); }}>
            <Text>Scroll to top</Text>
          </TouchableOpacity>
        </View>
    );
  }
}

var Thumb = React.createClass({
  shouldComponentUpdate: function(nextProps, nextState) {
    return false;
  },
  render: function() {
    return (
      <View style={styles.button}>
        <Image style={styles.img} source={{uri:this.props.uri}} />
      </View>
    );
  }
});

var THUMBS = [
'http://loremflickr.com/320/240?random='+Math.round(Math.random()*10000) + 1,
'http://loremflickr.com/320/240?random='+Math.round(Math.random()*10000) + 1,
'http://loremflickr.com/320/240?random='+Math.round(Math.random()*10000) + 1
];

THUMBS = THUMBS.concat(THUMBS); // double length of THUMBS
var createThumbRow = (uri, i) => <Thumb key={i} uri={uri} />;

var styles = StyleSheet.create({
  scrollView: {
    backgroundColor: '#6A85B1',
    height: 600,
  },
  horizontalScrollView: {
    height: 120,
  },
  containerPage: {
    height: 50,
    width: 50,
    backgroundColor: '#527FE4',
    padding: 5,
  },
  text: {
    fontSize: 20,
    color: '#888888',
    left: 80,
    top: 20,
    height: 40,
  },
  button: {
    margin: 7,
    padding: 5,
    alignItems: 'center',
    backgroundColor: '#eaeaea',
    borderRadius: 3,
  },
  buttonContents: {
    flexDirection: 'row',
    width: 64,
    height: 64,
  },
  img: {
    width: 321,
    height: 200,
  }
});

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

I uninstalled it on Genymotion. Then run react-native run-android to build the app. And it worked. Do try this first before running sudo ./gradlew clean, it will save you a lot of time.

---

For just restarting the computer fixed it. (My error was "module appRegistry is not a registered callable module (calling runapplication) js engine: hermes")

Another top answer that is missing here and might have worked was just to kill node processes:

killall -9 node

[ Module AppRegistry is not registered callable module (calling runApplication) ]

---

In my case, my index.js just points to another js instead of my Launcher js mistakenly, which does not contain AppRegistry.registerComponent().

So, make sure the file yourindex.jspoint to register the class.

---

My issue was fixed by increasing my inotify max_user_watches:

sudo sysctl fs.inotify.max_user_watches=1280000

---

For me it was a issue with react-native dependency on next version of react package, while in my package.json the old one was specified. Upgrading my react version solved this problem.

---

For me just i linked with react native as this way : react-native link

---

restart packager worked for me. just kill react native packager and run it again.

---

if you are facing this error in windows with android

open your root directory app folder and move into android folder .

     cd android 
     gradlew clean

start your app again react-native run-android

bhooom it works

---

npm start -- --reset-cache

Probably port is already in use. I face similar issue when i first run react-native run-android and then npm start. I solve it like this: First, get the id of the process running in port 8081: sudo lsof -i :8081
