React Native - undefined 不是对象（评估 'RNGestureHandlerModule.state'）

Question

我收到这个错误，这让我抓狂，我什至无法在 React Native 上启动一个简单的应用程序。我正在使用最基本的示例，使用一个新项目，但仍然会抛出此错误。我使用 react-navigation v3xx 有人请帮忙，因为我失去了理智，谢谢。这是我的代码：

import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View, Button, TouchableHighlight} from 'react-native';
import { createAppContainer, createStackNavigator, StackActions, NavigationActions } from 'react-navigation'; // Version can be specified in package.json


class Home extends React.Component {
  static navigationOptions = {
    title: "Home",
  }
  render() {
    return (
      <View style={styles.container}>
        <Text>Home Page</Text>
        <Button onPress={() => this.props.navigation.navigate('About')} title="All about me" />
      </View>
    );
  }
}

class AboutMeMe extends React.Component {
  static navigationOptions = {
    title: "All Me",
  }
  render() {
    return (
      <View style={styles.container}>
        <Text>Home Page</Text>
        <Button onPress={() => this.props.navigation.goBack()} title="<< Back" />
      </View>
    );
  }
}

const AppScreens = createStackNavigator({
  Home: Home,
  About: AboutMeMe
})

const App = createAppContainer(AppScreens);

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});


export default App;

Answer 1

npm install --save react-native-gesture-handler
react-native link react-native-gesture-handler

Answer 2

你好

由于 react 导航现在依赖于手势，因此您必须在安装 react-navigation 库后安装一个额外的库

运行从您的终端在您的项目中执行此命令

npm install --save react-native-gesture-handler

然后运行这个

react-native link react-native-gesture-handler

这些说明在这里有很好的解释

https://reactnavigation.org/docs/en/getting-started.html#installation

对于新的 React 导航版本

此致

React Native - undefined 不是对象（评估 'RNGestureHandlerModule.state'）

React Native - undefined is not an object(evaluating 'RNGestureHandlerModule.state')
