Question

我是新来的本地人。在实施反应导航时，我面临一个奇怪的问题。我在iOS模拟器上收到错误消息，“未定义不是一个对象（正在评估'RNGestureHandlerModule.State'）。在我的应用程序中无处使用手势识别器。

export default class App extends Component {
  render() {
    return (
      createStackNavigator({
        Home: {screen: HomeScreen},
      })
    )
    }
}

HomeScreen是一个简单的类：

export default class HomeScreen extends Component {
    render() {
        return(
            <View>
                <Text style={{marginTop: 80}}>Thi sis test</Text>
            </View>
        );
    }
}

我正在使用本机CLI。在安装反应导航时，我会收到一些警告

尝试一次：

删除node_modules和package-lock.json
npm安装
npm install-保存反应导航
npm install-保存react-native-gesture-handler
