模块 AppRegistry 不是已注册的可调用模块 [英] Module AppRegistry is not a registered callable module
问题描述
我从 React Native 开发开始,一开始就遇到了一个问题.尝试运行我的应用时出现错误:
I'm starting with React Native development and I encountered an issue in the very beginning. When trying to run my app I get errors:
Invariant Violation: Module AppRegistry 不是注册的可调用模块(调用 runApplication)
未处理的 JS 异常:不变违规:本机模块不能为空.
未处理的 JS 异常:不变违规:模块 AppRegistry 不是已注册的可调用模块(调用 runApplication)
Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)
Unhandled JS Exception: Invariant Violation: Native module cannot be null.
Unhandled JS Exception: Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)
我的 App.js:
import React, { Component } from 'react';
import { SafeAreaView } from 'react-native';
import DefaultRouter from './src/navigation/DefaultRouter'
export default class App extends Component {
render() {
return (
<SafeAreaView>
<DefaultRouter />
</SafeAreaView>
);
}
};
index.js:
import { AppRegistry } from 'react-native';
import App from './App';
import {name as appName} from './app.json';
AppRegistry.registerComponent(appName, () => App);
DefaultRouter.js:
DefaultRouter.js:
import { createSwitchNavigator, createAppContainer } from 'react-navigation';
import LoginScreen from '../screen/LoginScreen';
import DefaultTabBar from '../navigation/TabBar';
const DefaultRouter = createSwitchNavigator({
LOGIN_SCREEN: {
screen: LoginScreen
},
TAB_NAVIGATION: {
screen: DefaultTabBar
}
}, {
initialRouteName: 'LOGIN_SCREEN',
headerMode: 'none'
})
export default createAppContainer(DefaultRouter)
其他文件是简单的Component
子类.
Other files are simple Component
subclasses.
无论我是从 Visual Studio Code 还是从带有 react-native run-ios
The issue manifests regardless if I run the app from Visual Studio Code or from terminal with react-native run-ios
我查看了现有的答案,但没有找到任何可以为我指明正确方向的内容:
React-Native:Module AppRegistry 不是注册的可调用模块
React Native:Module AppRegistry 不是一个注册的可调用模块(调用 runApplication)
模块 appregistry 不是注册的可调用模块(调用 runApplication)模块 AppRegistry 不是注册的可调用模块和找不到变量:常量
React Native 模块 AppRegistry 不是注册的可调用模块>
模块 AppRegistry 不是已注册的可调用模块仅在发布配置中
I looked through existing answers and I didn't find anything that could point me in the right direction:
React-Native: Module AppRegistry is not a registered callable module

我被困住了,我不知道从哪里开始
I'm stuck and I don't know where to go from here
